## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Project Status: Current project status: The project is Ongoing and healthy. We had a successful Cassandra Summit back in December and we're lined up for a C* track at Community Over Code EU and CoC US in 2024. We're pushing towards a 5.0 release with many new features the community is excited for. Stabilizing that now, and hope to have that out H1'24. Committer roster continues to grow with diverse folks from many different areas, and the subprojects are providing smoother easier on-ramps into the ecosystem for new contributors as hoped. Issues for the board: No issues for the board at this time. ## Membership Data: Apache Cassandra was founded 2010-02-16 (14 years ago) There are currently 79 committers and 36 PMC members in this project. The Committer-to-PMC ratio is roughly 5:3. Community changes, past quarter: - No new PMC members. Last addition was Dinesh Joshi on 2021-05-19. - Bret McGuire was added as committer on 2024-02-07 - Alexandre Dutra was added as committer on 2024-01-03 - Brad Schoening was added as committer on 2024-02-09 - Francisco Guerrero was added as committer on 2023-11-28 - Mike Adamson was added as committer on 2023-12-10 - Maxim Muzafarov was added as committer on 2024-01-08 - Olivier Michallat was added as committer on 2024-01-18 NOTE: When we bring in a subproject, our approach is to offer the commit bit to the top contributors on that project (barring any argument otherwise by existing PMC / committers), so they can continue to work on that project with momentum. We don't want donating to the foundation to be a hit and run because people can't continue working on the thing they built or are blocked on review, etc. In the event a large project largely funded by one entity is donated to the foundation, we expect to see several people raised to committer that work for one company at that time. Since we treat "area of committing" as a social contract (i.e. only commit code to the area you know about; we don't enforce limitations on commit bit from a technical perspective), this doesn't represent any change in control or influence across the full project ecosystem. ## Project Activity: 5.0-beta1 was released on 2023-12-05. 4.1.4 vote passed morning of 2024-02-14 and should release shortly. Holiday periods are always slower for us, as are ramps up to a major release as people focus on burning down CI flakies. No exception this quarter, but activity remains healthy and within expectations. We're pushing to validate a 5.0 release and hope to fast-follow with 5.1 as soon as the Accord feature (distributed ACID transactions w/novel Paxos algorithm) is stabilized. ## Community Health: Participation on dev list, user list, forums, slack, etc continues at similar paces to previous years. Project remains healthy. ## Other notes: ### Subprojects, governance Cassandra isn't an umbrella project nor pushing to be one. We're a distributed system that has multiple dependencies and components in its ecocystem which only work with the core DB, and the core DB ultimately only works if they're present or some other component like them is (i.e. k8s operator, sidecar, driver, etc). Historically the drivers were in-tree then moved out; we've now brought them back in. The ecosystem is large enough that no one person can be deep experts in the entire set of codebases so we've split up to the "social contract" of a global commit-bit with agreed-upon expectations to not review or commit code in a place you're not familiar with. Not different than how we've always operated on the core database just with more clearly articulated boundaries. We require at least 3 PMC members to volunteer to be accountable for a subproject as we need at least 3 members to vote on releases and need the broader view of the ecosystem to integrate w/those projects. The entire PMC remains fully responsible for the health, integration, and releases of all subprojects. So far this has worked well. No sub-project will come into the ecosystem without a 100% explicit dependency on the core apache cassandra database. ### Planet Cassandra, mark management, marketing We've reached out to brand about handling potential mark infringement on https://cassandra.alteroot.org. We've had to go back and forth educating users and vendors on appropriate boundaries and balancing / excluding bias, as well as clear respect for the foundation and project's marks. The site continues to improve in this regard. We've had discussions with the folks who run Planet Cassandra about potentially donating the site to the ASF (dns record, hosting). They're very excited and receptive to this idea; the PMC hasn't had cycles to move on that yet due to holiday season and upcoming release. Also, ASF Infra has historically indicated to us a general reluctance to take on more domain name registrations or site hosting. We'll have to continue to thread the needle of allowing self-promoting, ASF project complementary content on that site that's by definition not vendor neutral while the PMC continues to push for keeping the entire property as both vendor-neutral and vendor-enabling as possible. Having the site under the foundation could only make this process easier for us to continue to refine; we'll continue to pursue that. Project marketing group has been renamed to comdev as seen as more fitting for an ASF project.
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Project Status: Current project status: the project is healthy and we're driving towards a 5.0 GA release, hopefully in CY 2023. Issues for the board: no issues require board attention at this time, but feedback on a number of open issues will be provided below. ## Membership Data: Apache Cassandra was founded 2010-02-16 (14 years ago) There are currently 72 committers and 36 PMC members in this project. The Committer-to-PMC ratio is 2:1. Community changes, past quarter: No new PMC members. Last addition was Dinesh Joshi on 2021-05-19. No new committers. Last addition was Patrick McFadin on 2023-03-13. Discussions are ongoing about new committers (Mike Adamson, Francisco Guerrero Hernandez, etc), both for the primary project but also subprojects we've brought in this year. We expect the Java Driver donation to lead to quite a few new committers as well. ## Project Activity: We're optimistic that we can get 5.0 to GA this calendar year; if it slips, however, that'd break us free from the "December release" pressure we have if we want to hit once a year CY releases, and many users are during change freeze from before Thanksgiving so aren't available to really heavily engage in testing during this window of time. ### Recent releases: 5.0-alpha2 was released on 2023-11-04. 5.0-alpha1 was released on 2023-09-08. 3.11.16 was released on 2023-08-20. ## Community Health: Community engagement in terms of dev and user ML, slack channels, meetups, etc. remains healthy. No concerns here, and we have a summit coming in early December for the project that should be good for the community. ## Other Updates ### PlanetCassandra: We continue to work with the folks from https://anant.us/ who put PlanetCassandra together on guiding their usage of the mark and keeping a neutral balance that's inviting to external vendors to participate. #### Site Contents: We've opened some discussions about the possibility of donating the site and the property to the ASF. Mark opened up a very helpful thread on our private@ clarifying some of the things we should work on w/Anant, and there are github issues tracking that work now. Patrick McFadin indicated that the code for PlanetCassandra is intended to be open sourced; I'll follow up with Rahul (w/Anant) on both this and the donation angle. While the pmc has approved, and has killswitch access credentials and full line-of-sight on all activities, it's not PMC managed at this time. It's not currently an ASF property and non-committers can and do submit content to the site. There's also news aggregation that takes place on the site (where we often discover mark violations as the content gets pulled in), which is a great way to see it in one place and be helpfully informing vendors about our brand requirements. A number of types of content has been identified as needing or being more appropriate to be on the formal project website and have since been moved. #### Domain: The owners of the domain registration (DataStax employees) state they have offered to donate the domain to the ASF multiple times but been repeatedly turned down. Not sure the details here; we will pursue this. https://cassandra.alteroot.org (Alteroot clone of Planet Cassandra) This site isn't maintained by the pmc or C* community. If brand could follow up with the maintainers of this site we'd appreciate it. ### Catalyst Program (formerly Cassandra MVP) Discussion continues with particular care taken to funnel all activity appropriate for ASF merit into those existing channels, and clearly demarcating what the program is intended to target (community building efforts) vs. committer (project building, code building efforts). ### Java Driver Donation Mick forgot to add general@incubator on the vote thread so we're working through anything that was missed there, e.g. some issues legally blocking distribution. We're receiving immediate help on this so we're unblocked and making progress. ### Subprojects Ecosystem is evolving and going well; as discussed above we're moving to raise committers for existing sub-projects and should be able to do the same for the Java Driver this quarter ### Dependencies and clarification on generative AI See https://issues.apache.org/jira/browse/LEGAL-656. The author of the jvector library our project took a dependency on was very clear about their usage of generative AI during authorship of the work and some PMC members were concerned that might have implications with us taking a dependency on this for a core feature in our upcoming release. We got clarification on the legal JIRA and the authors of the work clarified their compliance with ICLA clauses #5 and #7 in the comments on https://issues.apache.org/jira/browse/CASSANDRA-18715, clarifying any ambiguity there on rights and assignment.
@Rich: follow up on subproject governance on board list
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Project Status: Current project status: Ongoing Issues for the board: No issues for the board at this time ## Membership Data: Apache Cassandra was founded 2010-02-16 (13 years ago) There are currently 72 committers and 36 PMC members in this project. The Committer-to-PMC ratio is 2:1. Community changes, past quarter: - No new PMC members. Last addition was Dinesh Joshi on 2021-05-19. - No new committers. Last addition was Patrick McFadin on 2023-03-13. ## Project Activity: We've had new releases on our 2 primary lines, 4.1.3 and 4.0.11, both back in July. We're on track for releasing a very significant major (5.0) with many novel new features, and this is planned to cut within a year of our last major .0 release as committed to the community. Discussions around donations of the Java and python drivers from DataStax to the Apache Foundation have resumed now that IP clearance has been worked through. ## Community Health: Engagement on dev list and user list as well as dev and user slack remains healthy and consistent; we expect to see a bump in both as we cut an alpha for 5.0 and start calling on the community to test out the new features coming up. Contributions leading up to the new release remain high. Some stats: - dev@cassandra.apache.org had a 9% increase in traffic in the past quarter (814 emails compared to 741) - 488 commits in the past quarter (17% increase) - 77 code contributors in the past quarter (50% increase) ## Conversation from the last board report > Having a look at your "pr@" list... Thanks for the feedback; we're looking into this. > Going through your mailing list subscriptions I noticed a large number of non > PMC members and non ASF Members being subscribed. Some are committers and > some absolutely not related to the project... - povel.y@gmail.com, jonathan.haddad@gmail.com are PMC members. - We know who Prashant Malik and Avinash Lakshman are. They've declined PMC membership. - Looks like Kannan is a committer on HBase but nobody on the PMC has stepped forward as knowing him. To our knowledge he's not active in the Cassandra Community or on the project. > I also stumbled over your marketing@ list... > it feels as if all of this stuff is run by Datastax employees... to me it all > looks very corporaty and not quite sure this is how things should be done > for an apache open-source project. We discussed the creation of this list on dev@ here: https://lists.apache.org/thread/cd75fx95l827bdf7om9v52zp414vjmv1 and settled via lazy consensus. Patrick drove establishing the list on the ML but organization is primarily being led by people not employed by DataStax, and there are regularly participants from Constantia, Axon, Instaclustr, Aiven, and PMC members employed by various other companies on these calls. The meetings and minutes are all under PMC and ASF infra control here: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=240883297 > Patrick McFadin who sort of feels like he's "running cassandra marketing" and > is "only" a committer in the project. We've been working on adjusting our bar for the commit bit for a few years now (see email thread from Jon Haddad on private@ from April 2022 for some perspectives). Raising doc contributors in early 2022 and Patrick as a non-code, community committer earlier this year are steps in the right direction. More work to be done. > The website PlanetCassandra.org seems to be considered the most important > source of education in the meeting minutes for "management meetings" > (https://docs.google.com/document/d/1_73-iSjo1ZKKFn410rOCqNctnhNJOFLvbVA225OdrXY), > while I didn't see any explicit mention of DataStax, the domain however > belongs to DataStax. I'm not sure what the "management meetings" bit is referring to here, but the stated goals of cassandra.apache.org vs. planet cassandra are long-term durable education vs. short-term, user-led use-case sharing and social connectivity. We've had a lot of discussion about demarcations between the two sites as well as the cost/benefit of having 2 sites serving different personas and needs, and friction w/contribution of content to cassandra.apache.org vs. other sites, and these conversations are still ongoing. Of note, the PMC has admin access to Planet Cassandra's site and all socials.
@Justin: follow up on brand usage
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Issues: There are no issues requiring board attention. ## Membership Data: Apache Cassandra was founded 2010-02-16 (13 years ago) There are currently 72 committers and 36 PMC members in this project. The Committer-to-PMC ratio is 2:1. Community changes, past quarter: - No new PMC members. Last addition was Dinesh Joshi on 2021-05-19. - Patrick McFadin was added as committer on 2023-03-13 ## Project Activity: 3.11.15 was released on 2023-05-05. 4.0.9 was released on 2023-04-14. 4.1.1 was released on 2023-03-21. The 3.0 line continues to have special dispensation as our oldest supported release; when 5.0 releases we'll be dropping support for 3.0 and 3.11 both, leaving 4.0, 4.1, and 5.0 as our supported lines. Continued releases on the 4.0 line (post major stabilization) and 4.1 line (release line with significant operator tooling and stability features added) has seen good uptake in migration without any major surprises in terms of defects. There's a significant amount of work leading up to the 5.0 release; we have not yet concluded when to set a drop-dead date to cut the release as there's healthy tension between wanting to keep to a healthy yearly cadence and some very significant new features (multi-key transactions w/1 round-trip uncontended, strongly consistent cluster topology, some major data structure enhancements). No blockers and communication is healthy here. ## Community Health: We expect to see several committer nominations in the near future when the CEP-28 work lands (Spark bulk reader / writer in the Sidecar). These will be our first committers in an ecosystem subproject since we codified our governance structure for subprojects recently. Activity is picking up as we head into spring and summer, as well as the expected upcoming major 5.0 release. Some highlights: dev@cassandra.apache.org had a 58% increase in traffic in the past quarter (794 emails compared to 500) user@cassandra.apache.org had a 42% increase in traffic in the past quarter (151 emails compared to 106) 267 issues opened in JIRA, past quarter (25% increase) 190 issues closed in JIRA, past quarter (43% increase) 401 commits in the past quarter (45% increase) Moving some of our major work (mentioned above) into feature branches rather than on personal forks has given much more visibility into the amount of attention going into these major efforts and been effective in attracting more collaboration.
WHEREAS, the Board of Directors heretofore appointed Michael Semb Wever (mck) to the office of Vice President, Apache Cassandra, and WHEREAS, the Board of Directors is in receipt of the resignation of Michael Semb Wever from the office of Vice President, Apache Cassandra, and WHEREAS, the Project Management Committee of the Apache Cassandra project has chosen by vote to recommend Josh McKenzie (jmckenzie) as the successor to the post; NOW, THEREFORE, BE IT RESOLVED, that Michael Semb Wever is relieved and discharged from the duties and responsibilities of the office of Vice President, Apache Cassandra, and BE IT FURTHER RESOLVED, that Josh McKenzie be and hereby is appointed to the office of Vice President, Apache Cassandra, to serve in accordance with and subject to the direction of the Board of Directors and the Bylaws of the Foundation until death, resignation, retirement, removal or disqualification, or until a successor is appointed. Special Order 7I, Change the Apache Cassandra Project Chair, was approved by Unanimous Vote of the directors present.
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Issues: No action required from the board. We are still in a grace period before removing all older deb and rpm packages from dist.a.o and archive.a.o . Newer releases are now only found on apache.jfrog.io The vulnerability reported in December: around yaml parsing; is evaluated as non-critical and does not qualify as a CVE. Surface area is restricted to trusted operators. Yaml loading has been hardened as an extra line of defence: https://issues.apache.org/jira/browse/CASSANDRA-18150 Further information on CVEs we have evaluated, and suppressed, as not relevant can be found in https://github.com/apache/cassandra/blob/trunk/.build/dependency-check-suppressions.xml ## Membership Data: Apache Cassandra was founded 2010-02-17 (13 years ago) There are currently 72 committers and 36 PMC members in this project. The Committer-to-PMC ratio is roughly 9:5. Community changes, past quarter: - No new PMC members. Last addition was Dinesh Joshi on 2021-05-20. - The latest new committer is Patrick McFadin. Added last week, his id creation still in progress. ## Project Activity: The project planned the Cassandra Summit, a Linux Foundation Event, for March. We received a record amount of submitted talks. Due to the current economic environment the event has been moved back to December 12-13th. The existing date will host instead a new online event: Cassandra Forward. https://lists.apache.org/thread/g4rsqjysn4fqw34z6ro5q6ywml6mnrzd In December we saw the Cassandra Day China event. We are working on making it easier for anyone to host and repeat our Cassandra Day events. https://cassandra.apache.org/_/events/20221222-cday-china.html The project has created a marketing@ ML and a dedicated Publicity & Marketing Group that meets monthly. Media and Social activity continues in collaboration with the individuals from Constantia. https://lists.apache.org/thread/cd75fx95l827bdf7om9v52zp414vjmv1 Additional governance rules have been created to cater for the inclusion of subprojects and the growing community ecosystem. This includes the notion of partial, or per-subproject, committers. This is socially enforced in the project. https://lists.apache.org/thread/tgbqpq5x03b7ssoplccxompxj6d1gw90 Recent releases: - 4.1.0 (GA) was released on 2022-12-13. - 4.1-rc1 was released on 2022-11-22. - 3.11.14 was released on 2022-10-24. 4.0.8 is cut and being voted on. 3.0.29 and 3.11.15 are being cut. The PMC Chair will rotate before the next board report. ## Community Health: The community can be considered healthy and growing. Cassandra project status updates are emailed regularly to dev@, these are worth reading for a more detailed view on current state of affairs in the project. See https://s.apache.org/0heaa
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Issues: Per INFRA's notice, all our debian and redhat packages on dist.a.o will be removed. These convenience binaries are already on apache.jfrog.io . Newer releases are now only found on apache.jfrog.io. We are in a grace period before removing all older packages from dist.a.o and archive.a.o Answering rbowen's question from last report, the project's involvement in the Grace Hopper Open Source Day September conference was primarily offering mentoring to some of our lhf jira tickets, and was with PMC approval. ## Membership Data: Apache Cassandra was founded 2010-02-17 (13 years ago) There are currently 71 committers and 36 PMC members in this project. The Committer-to-PMC ratio is roughly 9:5. Community changes, past quarter: - No new PMC members. Last addition was Dinesh Joshi on 2021-05-20. - No new committers. Last addition was Jacek Lewandowski on 2022-07-14. ## Project Activity: There has been numerous events, 9 different Cassandra Days (Europe, Asia, USA), and our participation in ApacheCON. With the Cassandra project rebuilding its momentum and looking to build a more diverse community, ApacheCON occurred at the perfect time for us. From bringing new contributors into the loop with what's possible with the technology (the invisible roadmap), to spending time with them to re-affirm the community's open (and welcoming) position to all commercial actors, to just a focus on renewed energy among the project's existing committers. We are very thankful for everyone that worked so hard to make it happen. The project is now planning Cassandra Summit, a Linux Foundation Event, for next March. Will be hybrid, the onsite at San Jose. CFP is open and we are actively looking for sponsors. Due to the increase in events the Cassandra website now has a dedicated page for all community, and PMC+Trademarks approved, events: https://cassandra.apache.org/_/events.html Media and Social activity continues in collaboration with the individuals from Constantia. This is proving to be of critical value, delivering quality to the community that the engineering community struggles with. The PMC continues to work with Constantia to ensure things are in accordance with ASF requirements and values, but this is now only a formality. Recent patch releases were: 4.1-beta1 was released on 2022-10-12. 4.0.7 was released on 2022-10-24. 4.0.6 was released on 2022-08-25. 3.11.14 was released on 2022-10-24. 3.0.28 was released on 2022-10-23. The current priority in the community remains getting 4.1 to GA. Fixing a small handful of flaky tests, that fail 1:100 or 1:1000 runs, on the ASF CI cluster of donated heterogenous agents, amongst our test suite of ~50k tests, remains an interesting and time-consuming pursuit. The project is discussing how we can improve this situation without becoming dependent on proprietary CI solutions (like circleci). Development over the next year looks to be ramping up with the CEPs in progress, putting additional pressure on the need to stabilise and mature our CI. Additional testing frameworks need to be plugged in and made available to the public, particularly integrating our exploratory fuzz testing framework. ## Community Health: The community can be considered healthy and growing. Cassandra project status updates are emailed regularly to dev@, these are worth reading for a more detailed view on current state of affairs in the project. See https://s.apache.org/0heaa
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Issues: Per INFRA's notice all debian and redhat packages on dist.a.o will be removed, as they are already checked and signed per disto norms and the project does not wish to add superfluous checks and sigs (and have to re-vote on all past releases). The project will host these convenience binaries instead on apache.jfrog.io (which is also better purposed for such). ## Membership Data: Apache Cassandra was founded 2010-02-17 (12 years ago) There are currently 71 committers and 36 PMC members in this project. The Committer-to-PMC ratio is roughly 9:5. Community changes, past quarter: - No new PMC members. Last addition was Dinesh Joshi on 2021-05-20. - Jacek Lewandowski was added as committer on 2022-07-14 ## Project Activity: Project releases since last report: 4.1-alpha1, 4.0.5, 4.0.4, 3.11.13 and 3.0.27. The community's focus is currently on fixing flaky tests to be able to release 4.1-beta1. Progress is visible at https://s.apache.org/usdv9 The project organised the Cassandra World Party in the beginning of August, and is helping to organise Cassandra Days Berlin later in August and ApacheCon in October. The Cassandra track received more than three times as many talks as we could accept. More Cassandra Days are planned this year and next. The community will also participate in the Grace Hopper Conference in September. Community blog posts and changelog articles continue to come out on a regular basis, thanks to Chris Thornett, Diogenese Topper and Erick Ramirez. 14 blogs have been published in the past quarter, these include feature deep-dives, project activity reports (changelogs), contributor interviews, and company case studies. ## Community Health: Community health is strong. New contributors continue to appear. Keeping a stable trunk remains a challenge. Particularly when suites of ~50k tests can be run on different hardware and CI systems. Average test failures on builds for each branch continue to drop (bc lots of hard work). Cassandra project status updates are emailed regularly to dev@, these are worth reading for a more detailed view on current state of affairs in the project. See https://s.apache.org/0heaa
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Issues: There are no issues requiring board attention. ## Membership Data: Apache Cassandra was founded 2010-02-16 (12 years ago) There are currently 70 committers and 36 PMC members in this project. The Committer-to-PMC ratio is roughly 9:5. Community changes, past quarter: - No new PMC members. Last addition was Dinesh Joshi on 2021-05-19. - Anthony Grasso was added as committer on 2022-02-17 - Alex Sorokoumov was added as committer on 2022-03-21 - Erick Ramirez was added as committer on 2022-02-11 - Lorina Poland was added as committer on 2022-02-17 Anthony, Erick, and Lorina were contributors to the website and docs. Their inclusion as committers came as a result of the PMC agreeing to broaden the scope and trust to who could be committers. ## Project Activity: The cassandra-4.1 release branch was created on the 1st May. The community has held its agreement to a yearly major release cadence. Some statistics on the last years worth of work are: - 89 unique contributors - 498 jira issues (43% bugs) - over 3k files touched - over 65k added LOC, >310k deleted LOC The community will now maintain four release branches: 3.0, 3.11, 4.0, 4.1; over the next year and then (next May) will drop maintenance of both the 3.0 and 3.11 branches. Recent releases: 4.0.3 was released on 2022-02-17. 3.0.26 was released on 2022-02-11. 3.11.12 was released on 2022-02-11. New release 4.0.4, 3.11.13, 3.0.27 are currently being voted on. An interview with GigaOm was recently done, it has not yet been published. ## Community Health: Keeping a stable trunk remains a challenge. Test failures on 4.0 remain low (single-digit) and serve as a control test that the CI infrastructure is working (ci-cassandra.a.o still suffers high saturation and on occasion full disks). While in trunk (4.1) over the past year the failures have increased and are typically collateral damage from poorly written past tests and/or unforeseen setup/teardown requirements. These failures need to be address before any releases are cut off the 4.1 branch. The number of tests in trunk has increased significantly, with a 30% increase in test LOC. The community has introduced a build lead role that rotates every week, to keep track of failures and CI infra, ensuring test failures are associated to a jira ticket. This work is facilitated with the use of the Butler tool/website. Community blog posts and changelog articles continue to come out on a regular basis, thanks to Chris Thornett, Diogenese Topper and Erick Ramirez. Efforts are also underway around coordinating and pushing marketing efforts. And a number of folk are organising the Cassandra track at the ACNA, the number of submissions remain low and more effort will be required to get the word out. Cassandra project status updates are emailed regularly to dev@, these are worth reading for a more detailed view on current state of affairs in the project. https://lists.apache.org/list?dev@cassandra.apache.org:lte=2y:%22Cassandra%20project%22%20%22status%20update%22

## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Issues: There are no issues requiring board attention. ## Membership Data: Apache Cassandra was founded 2010-02-17 (12 years ago) There are currently 66 committers and 36 PMC members in this project. The Committer-to-PMC ratio is roughly 2:1. Community changes, past quarter: - No new PMC members. Last addition was Dinesh Joshi on 2021-05-20. - No new committers. Last addition was Sumanth Pasupuleti on 2021-10-27. ## Project Activity: There has been no releases this quarter. Most activity and community focus has been on trunk development which will not see a release until May. Patch releases 4.0.2 and 3.11.12 are quite probable in the near term. A lot of effort is still going into CI and establishing a Stable Trunk development approach. The introduction of https://butler.cassandra.apache.org/ and a rotating build lead role is helping to correlate CI results to trends and to jira tickets. ## Community Health: Community health is strong. Extra effort has been put into regular website content and blogs, and to the twitter account. The twitter account @cassandra is aiming to post twice a day. A quick sample survey showed >20% of our users have upgraded to 4.0 Cassandra project status updates are emailed regularly to dev@, these are worth reading for a more detailed view on current state of affairs in the project. https://lists.apache.org/list?dev@cassandra.apache.org:lte=2y:%22Cassandra%20project%22%20%22status%20update%22
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Issues: No issues to raise with the board this quarter. ## Membership Data: Apache Cassandra was founded 2010-02-17 (12 years ago) There are currently 66 committers and 36 PMC members in this project. The Committer-to-PMC ratio is roughly 2:1. Community changes, past quarter: - No new PMC members. Last addition was Dinesh Joshi on 2021-05-20. - Aleksei Zotov was added as committer on 2021-09-21 - Adam Holmberg was added as committer on 2021-08-10 - Sumanth Pasupuleti was added as committer on 2021-10-27 ## Project Activity: Three patch releases have been published this quarter. Lots of new activity on all fronts, often an increase from 25 to 60% (mailing lists, pull requests, jiras, etc). Commits being merged has dropped, but that is due to current activities, post the 4.0 release and its feature freeze being lifted, shifting to CEPS and planning major new features. ## Community Health: Community health is strong and improving. The community is finding its feet with its new Cassandra Enhancement Proposal (CEP) process, and collaborating across a more diverse landscape. Efforts continue to ensure newcomers are attracted and welcomed. Maintaining CI test results, while accelerating dev efforts is also an ongoing focus. Cassandra project status updates are emailed regularly to dev@, these are worth reading for a more detailed view on current state of affairs in the project.
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Issues: There are no issues requiring board attention. ## Membership Data: Apache Cassandra was founded 2010-02-17 (11 years ago) There are currently 64 committers and 36 PMC members in this project. The Committer-to-PMC ratio is roughly 8:5. Community changes, past quarter: - Dinesh Joshi was added to the PMC on 2021-05-20 - Adam Holmberg was added as committer on 2021-08-10 - Jon Meredith was added as committer on 2021-07-29 - Caleb Rackliffe was added as committer on 2021-05-14 ## Project Activity: Recent releases: 4.0.0 was released on 2021-07-26. 4.0-rc2 was released on 2021-06-30. 3.11.11 was released on 2021-07-28. 3.0.25 was released on 2021-07-28. The 4.0.0 release was a major milestone, years in the making. With coordination by ASF Press (Sally Khudairi) and Constantia (Melissa Logan) there was lots of media attention. The 4.0.0 release took four staging attempts and three voting rounds. PMC involvement and willingness to appropriately veto releases is demonstrating the community's seriousness for high quality releases. In coordination with the 4.0.0 release, a new design of the website was launched. The new version changes from ReStructuredText, Sphinx and Jekyll, to Asciidoc and Antora. This includes new content contributions from vendors and book authors, as well as making it easier to provide versioned docs for each release and for different languages. More information on can be read in our last Project Status email report: https://lists.apache.org/thread.html/r102752c080db48e34daadd575d11714ddfc6f773810c7a82556c05d3%40%3Cdev.cassandra.apache.org%3E ## Community Health: The reporter statistics report the project as Super Healthy to which we agree. This quarter has been a highlight for the project. The discussion of encouraging new and active contributors continues. This includes the topics of better visualising contributor metrics, JIRA ticket hygiene, establishing the Cassandra Enhancement Proposals (CEP) process and practice, and addressing our limited Reviewer capacity. For JIRA ticket hygiene we are looking into JIRA automations to notify on stale tickets, and to eventually transition such tickets to more appropriate statues. For contributions metrics we have evolved Subversion's contribulyze.py statistics for our needs. These statistics, currently under evaluation, are available for different time periods here: https://nightlies.apache.org/cassandra/devbranch/misc/contribulyze/html/ For CEPs, with development on Cassandra 4.1 now active, a number of new CEPs in action are helping to iron out the finer details. ref: https://lists.apache.org/thread.html/r232a87ccd0c5c08ce9c40cf8e5936c47270b59ff5d94d1fb33a80f21%40%3Cdev.cassandra.apache.org%3E For Reviewer capacity we remain challenged. The project requires two reviewers on most code contributions, or two committers involved on any ticket. On the more involved areas of the codebase we typically see three or more involved. This is critical for the quality and safety of end-users' data, but places a burden on the project to find enough volunteers and keep contributions from stagnating.
## Description: Apache Cassandra software is a highly scalable second-generation distributed database. ## Issues: The project is waiting on clear documentation on the policy of the permitted composition of releases. The project is following the same release procedure it has for the past 11 years, as it was developed in the incubator. This procedure adheres to all current documentation of the ASF's release policy. The project was recently told this was not the case. The project requests this policy documentation be clarified. The project has applied what it presumes to be an accurate and efficient fix to trunk, but not on our older release branches: 2.2, 3.0 and 3.11. Addressing the issue involved significant effort over a number of codebases, and distracted many from fixing critical technical issues in the 4.0 code. This was the project's first 4.0 RC release after many years of feature freeze (on the whole project) as it focuses on stabilisation efforts. At a critical point in time for the project, with a number of community events coordinated, it was unfortunate timing for the issue to be raised and demanded to be immediately fixed. The project is interested in improving how communication happens across the ASF. Recent interjections have disrupted the health of the community. Despite best intentions to be constructive the issues were raised in an authoritative manner over the project, and with only a little homework were quickly proven as factually wrong. While these issues could have been easily raised by a contributor without controversy, they also demonstrate the challenges of good communication. ## Membership Data: Apache Cassandra was founded 2010-02-17 (11 years ago) There are currently 61 committers and 35 PMC members in this project. The Committer-to-PMC ratio is roughly 8:5. Community changes, past quarter: - Paulo Motta was added to the PMC on 2021-02-09 - Berenguer Blasi was added as committer on 2021-04-01 - Štefan Miklošovič was added as committer on 2021-05-02 The PMC currently consists of 35 members. 38% work at Apple, 22% at DataStax. The remaining 40% do not share the any same employer. The project considers this a healthy ratio. ## Project Activity: Recent releases: 4.0-rc1 was released on 2021-04-25. After a previous failed attempt. 3.0.24 was released on 2021-02-01. 3.11.10 was released on 2021-02-01. A newly designed website was launched for Apache Cassandra. With a heavy focus on the community and the extent of Cassandra deployments. Work is ongoing with contributions to the documentation and providing versioned documentation for each release. The community is collecting its own website traffic stats using a self-hosted Plausible server. The project recommends ASF Infra considers evaluating hosting this for all projects. https://plausible.cassandra.apache.org/cassandra.apache.org The community organised the Apache Cassandra World Party, hosting presentations and lightning talks in three timezones (APAC, EMEA, AMER), attracting over a thousand participants. https://hopin.com/events/apache-cassandra-4-0-world-party Trademark issue with Aiven remain in discussion. ## Community Health: All MLs have seen a significant increase in traffic, attributed to the RC release of 4.0, the feature freeze on trunk ending, and ongoing efforts to build community momentum. The PMC takes regular discussions on how to improve community growth and encouraging contributors. The last thread on it received a lot of engagement, especially as new contributors are appearing now that the feature freeze on trunk is lifted. This thread started before a Board member interjected about not enough being done. Focus is currently on reviewer bandwidth and Jira ticket hygiene. https://lists.apache.org/thread.html/ra364097c4dafeeac52934bbf08687b3b54445c5758824c53bcb901b0%40%3Cdev.cassandra.apache.org%3E
## Description: The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data. Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages. ## Issues: There are no issues to bring to the board's attention at this time. The PMC has been actively dealing with CVE and trademark issues, as they are brought to our attention. ## Membership Data: There are currently 59 committers and 34 PMC members in this project. The Committer-to-PMC ratio is roughly 8:5. PMC and committer additions this quarter: - Adding a new PMC member in currently in progress. The last PMC addition was Michael Semb Wever on 2020-04-09. - Ekaterina Dimitrova was added as committer on 2020-12-10 - Yifan Cai was added as committer on 2020-12-19 ## Project Activity: The project's focus remains on testing 4.0 beta, with trunk remaining in feature freeze. A 4.0 RC release is looking likely in the this quarter. A 4.0 GA looks to be soon after. This progress is being regularly reported with the 'Cassandra 4.0 Status' emails on the dev ML, and can also be visualised via the jira board: https://issues.apache.org/jira/secure/RapidBoard.jspa?rapidView=355&view=detail&selectedIssue=CASSANDRA-16382&quickFilter=1661 The releases 3.0.24 and 3.11.10 address CVE-2020-17516. This took some time to release and report but it was being actively addressed during what appeared the waiting period. Furthermore, these releases were cut and published by a new release manager, a positive sign in seeing the release manager become a more rotating role. The community is receiving and publishing monthly changelog blogs, which include reaching out to users and getting use-case descriptions and quotes. There also looks to be momentum in Cassandra getting involved in GSoC 2021. Recent releases: * 3.0.24 was released on 2021-02-01. * 3.11.10 was released on 2021-02-01. * 4.0-beta4 was released on 2020-12-30. ## Community Health: The community appears to be in good health. The past quarter has seen a slight reduction in activity but that would appear to be only to do with the time of year.

Last addition was Michael Semb Wever on 2020-04-09. - Zhao Yang was added as committer on 2020-09-23 ## Project Activity: The project's focus remains on testing 4.0 beta, with the trunk code remaining in feature freeze. A 4.0 GA release is looking likely in the next quarter. The community continues to build momentum, with an increases in dev mailing list traffic, number of jira tickets closed, and in commits. There have been more releases than usual as the community has responded promptly to issues and bugs. Notable activities in the past quarter are: - Harry - a fuzz testing tool for the project, was donated, having gone through the Incubator's IP Clearance. - Discussions on the various Kubernetes Operators and whether to promote one, merge, or re-invent, continue with a healthy and engaged diversity between implementations. - The project's governance has become better agreed upon and documented, with the past quarter demonstrating it in play with the PMC trending to use the dev ML more than the private ML. - The project's website, and its documentation, is undergoing efforts to redesign and improve layout and navigation around the bulk of documentation that continues to be donated to the project. Recent releases: * 2.2.19 was released on 2020-11-04. * 3.0.23 was released on 2020-11-04. * 3.11.9 was released on 2020-11-04. * 4.0-beta3 was released on 2020-11-04. * 2.1.22 was released on 2020-08-31. * 2.2.18 was released on 2020-08-31. * 3.0.22 was released on 2020-08-31. * 3.11.8 was released on 2020-08-31. * 4.0-beta2 was released on 2020-08-31. ## Community Health: We feel the community is building momentum. Folk are anxious to get 4.0 released and to end the feature freeze encouraging the larger contributions and new contributors into the project. This has energised the community in what appears to be the last stretch of testing for 4.0.

Last addition was Michael Semb Wever on 2020-04-09. - David Capwell was added as committer on 2020-07-22 ## Project Activity: This has been a busy quarter: - We have 19 talks accepted for ApacheCon - We have received a proposal for a sizeable code donation of all the client driver libraries maintained by DataStax. We are currently discussing how this would work in terms of onboarding committers, integrating with community, and structuring of artifacts and release cadences. We will most likely import the java-driver first (following the incubator process for donation) as a trial run to work out the process. - DataStax has also offered to donate a substantial amount of documentation to the project along with resources for maintenance - We have released 4.0-beta1 and received a good amount of press Recent releases: 3.0.21 was released on 2020-07-29. 2.2.17 was released on 2020-07-24. 3.11.7 was released on 2020-07-24. 4.0-beta1 was released on 2020-07-20. ## Community Health: Between the number of talks submitted for ApacheCon, the recent donations, and the interest from 4.0-beta1, we feel the community is doing quite well. There is daily participation on both the user and dev slack channels and the number of users therein continues to increase. Traffic to dev@cassandra.apache.org had a 21% increase in the past quarter.

This quarter, we were able to come to an amicable resolution with AWS concerning the use of our Apache Cassandra trademark in their Cassandra SaaS offering. The AWS folks were amenable and gracious through the whole process and have rebranded to "AWS Keyspaces." ## Membership Data: Apache Cassandra was founded 2010-02-17 (10 years ago) There are currently 55 committers and 34 PMC members in this project. The Committer-to-PMC ratio is roughly 7:5. Community changes, past quarter: - Michael Semb Wever was added to the PMC on 2020-04-09 - Jordan West was added as committer on 2020-04-29 ## Project Activity: 4.0-alpha4 was released on 2020-04-24 as we continue to gather feedback on our upcoming 4.0 release. The following maintenance releases were made for existing versions: - 2.2.16 was released on 2020-02-14 - 3.0.20 was released on 2020-02-14 - 3.11.6 was released on 2020-02-14 ## Community Health: We have continued with weekly updates to the dev list on the progress of bugs and issues open for 4.0. There has also been a significant uptick in participation as more folks pitch in to help get our release out. The following statistics show this increased effort: - 232 issues opened in JIRA, past quarter (51% increase) - 217 issues closed in JIRA, past quarter (143% increase) - 242 commits in the past quarter (101% increase) - 60 code contributors in the past quarter (66% increase) - 168 PRs opened on GitHub, past quarter (162% increase) - 119 PRs closed on GitHub, past quarter (376% increase) Additionally, we have had some very robust discussions on guidelines for PMC membership as well as process based votes in general. We are working to produce some project level documentation so that we have a shared understanding of this for ourselves as PMC members and, more importantly, for our community.

Last addition was Dinesh Joshi on 2019-03-05. ## Project Activity: We released 4.0-alpha3 on 2020-02-06 to gather community feedback and get more folks actively involved in testing. We have started a detailed tracking board on JIRA and have been sending out regular updates on status. An example email can be found here: https://s.apache.org/r56u3 Other releases: - 2.2.15 was released on 2019-10-29. - 3.0.19 was released on 2019-10-29. Note: new releases of each 3.11, 3.0, and 2.2 branches are currently under vote. ## Community Health: We've had a substantial uptick in traffic over the past quarter as a result of folks getting back involved in the release of 4.0 after the holidays. The following stats are pertinent: - 79 issues closed in JIRA, past quarter (21% increase) - 115 commits in the past quarter (57% increase) - 35 code contributors in the past quarter (40% increase) - 63 PRs opened on GitHub, past quarter (36% increase) We continue to see an increase in user participation in both #cassandra and #cassandra-dev Slack channels. This is now our most popular avenue for helping new users. We are looking forward to our Apache Cassandra track at this years ApacheConNA and have again requested three days. CFP announcements for such have been sent to the dev and users mail lists.

The Committer-to-PMC ratio is roughly 3:2. Community changes, past quarter: - Chris Lohfink was added to the PMC on 2019-10-01 - No new committers this quarter. ## Project Activity: This quarter has been active. We have had a very successful ApacheCon with 2 well attended tracks over three days. Of the vendors there, five of them had Cassandra product offerings while two were focused exclusively on Cassandra. We have already begun talking a similar sized effort for ApacheCon NA 2020. We have begun migrating our site off of SVN as that has been a barrier to entry in accepting documentation patches in a timely manner. We have released two alphas of the upcoming 4.0 and received helpful feedback and bug reports from the community. All other active versions were released as well. A list of releases follows: - 2.2.15 was released on 2019-10-29. - 3.0.19 was released on 2019-10-29. - 3.11.5 was released on 2019-10-29. - 4.0-alpha2 was released on 2019-10-29. - 2.2.15 was released on 2019-10-29. ## Community Health: Interesting statistics from community health: - dev@cassandra.apache.org had a 163% increase in traffic in the past quarter (329 emails compared to 125) - 44 PRs opened on GitHub, past quarter (69% increase) - 20 PRs closed on GitHub, past quarter (53% increase) - 124 issues opened in JIRA, past quarter (-21% decrease) - 52 issues closed in JIRA, past quarter (-40% decrease) We think this reduction of new and closed issues in JIRA in conjunction with the rate of PRs addressed is indicative of the community efforts focused on the alpha releases of 4.0. Dev list traffic is up as a result of some good discussions regarding development processes (soon to be published), releases and documentation.

Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages. ## Issues: We have sent off a trademark violation to aiven.io and have not heard a response after five days. We have moved off of IRC onto the ASF's Slack Instance. This has (anecdotally as we don't have exact numbers) driven a large uptick in active conversations on both #cassandra and #cassandra-dev over their IRC counterparts. ## Membership Data: Apache Cassandra was founded 2010-02-17 (9 years ago) There are currently 54 committers and 32 PMC members in this project. The Committer-to-PMC ratio is roughly 7:4. We have had no new committers added this quarter. We think this may be the result of feature work being frozen and we are primarily focused on testing for our upcoming 4.0 release. Given that last quarter saw the addition of three committers, we do not see this as a negative for the project's health. Community changes, past quarter: - No new PMC members. Last addition was Alex Petrov on 2019-04-09. - No new committers. Last addition was Dinesh Joshi on 2019-03-05. ## Project Activity: We are eagerly anticipating this year's ApacheConNA as we have expanded our track to three days. We have been assigned a doc writer through Google Season of Docs and will begin working with them on our outstanding documentation projects shortly. ## Community Health: We are continue to track and prioritize issues as we approach 4.0: https://cwiki.apache.org/confluence/display/CASSANDRA/4.0%3A+Open+Issues+by+Component Interesting statistics this quarter: - dev@cassandra.apache.org had a 39% decrease in traffic in the past quarter (133 emails compared to 217) - 84 issues closed in JIRA, past quarter (35% increase) - 66 commits in the past quarter (17% increase) The dip in development list activity could be a result of the increased participation in our slack channel. We have both an increase in the number of commits and the number of closed issues for this quarter, so overall the numbers seem healthy.

We have already received four inbounds from potential documentation writers even though the program has not officially begun. Additionally, we have expanded our ApacheCon request to a two day track. The first day will be our developer centric conference known as Next Generation Cassandra Conference (NGCC). The second day will be a general-purpose sponsorship. We have already attracted a pair of sponsors and received some high-quality submissions from some of our largest users for both days of the conference. ## Health report: We are continue to track and prioritize issues as we approach 4.0: https://cwiki.apache.org/confluence/display/CASSANDRA/4.0%3A+Open+Issues+by+Component ## PMC changes: Alex Petrov was added to the PMC on Tue Apr 09 2019. There are currently 32 PMC members. ## Committer base changes: Three new committers were added this quarter, bringing our total to 54: - Dinesh Joshi was added as a committer on Tue Mar 05 2019 - Joey Lynch was added as a committer on Thu Feb 28 2019 - Vinay Chella was added as a committer on Sat Feb 23 2019 ## Releases: The project made the following releases this quarter: - 2.1.21 was released on Mon Feb 11 2019 - 2.2.14 was released on Mon Feb 11 2019 - 3.0.18 was released on Mon Feb 11 2019 - 3.11.4 was released on Mon Feb 11 2019 ## Mailing list activity: We had a marginal fall off of mail list activity this quarter, but the overall traffic to both dev and user lists is still healthy. dev@cassandra.apache.org: - 1554 subscribers (down -43 in the last 3 months): - 279 emails sent to list (273 in previous quarter) user@cassandra.apache.org: - 2945 subscribers (down -45 in the last 3 months): - 660 emails sent to list (436 in previous quarter) ## JIRA activity: - 112 JIRA tickets created in the last 3 months - 65 JIRA tickets closed/resolved in the last 3 months

We have also requested a day long track for ApacheCon 2019 and are looking forward to participating. ## Health report: We are continue to track and prioritize issues as we approach 4.0: https://cwiki.apache.org/confluence/display/CASSANDRA/4.0%3A+Open+Issues+by+Component We have a number of community members actively testing snapshots of 4.0 with replays of production workloads using audit logging (http://cassandra.apache.org/blog/2018/10/29/audit_logging_cassandra.html). This in combination with recent improvements in property-based testing (http://cassandra.apache.org/blog/2018/10/17/finding_bugs_with_property_based_testing.html) has led to the discovery of a number of bugs that would have, in previous major releases, been left for users to discover on their own. ## PMC changes: There are currently 31 PMC members. No new PMC members added in the last 3 months. The last PMC addition was Stefania Alborghetti on Thu Sep 27 2018. ## Committer base changes: There are Currently 51 committers. Chris Lohfink was added as a committer on Sat Dec 01 2018 ## Releases: We recently made the following releases across four versions: - 2.1.21 was released on Mon Feb 11 2019 - 2.2.14 was released on Mon Feb 11 2019 - 3.0.18 was released on Mon Feb 11 2019 - 3.11.4 was released on Mon Feb 11 2019 ## Mailing list activity: Mailing list activity is down for both user and dev lists. This may just be a result of nothing new to discuss given the lack of a major release. dev@cassandra.apache.org: - 1597 subscribers (down -27 in the last 3 months): - 361 emails sent to list (460 in previous quarter) pr@cassandra.apache.org: - 14 subscribers (up 1 in the last 3 months): - 141 emails sent to list (585 in previous quarter) user@cassandra.apache.org: - 2996 subscribers (down -23 in the last 3 months): - 481 emails sent to list (791 in previous quarter) ## JIRA activity: - 128 JIRA tickets created in the last 3 months - 128 JIRA tickets closed/resolved in the last 3 months

the perfect platform for mission-critical data. Cassandra's support for
replicating across multiple datacenters is best-in-class, providing lower
latency for your users and the peace of mind of knowing that you can survive
regional outages.
## Issues:
There are no issues requiring board attention at this time.
## Activity:
Several months ago, DataStax had made a change around an assignment of IP
clause in the ICLA for their Java Driver (which serves as a reference
implementation for the native protocol) that had prevented some users from
contributing. We were able to work with them to get that change rolled back.
This was a pretty serious issue given that some features in-tree rely on the
driver as a dependency. We have asked to have the driver donated to the
project and they have declined.
We have recently voted to begin the process of importing the GoCQL driver, but
that project's policy of making every contributor an author may make this
impossible given we would have to get signoff from each person:
https://github.com/gocql/gocql/blob/master/AUTHORS
This quarter, we started a series of blog posts and have had a steady stream
of community contributions for content: http://cassandra.apache.org/blog/
The blog has been well received and is serving as a method for distributing
information about the changes we have been making for 4.0.
## Health report:
Project activity is up substantially in the context of development
discussions. We have moved into a freeze in anticipation of testing 4.0 and
have worked with the community to put together a testing plan for which many
members of the community have already signed up:
https://cwiki.apache.org/confluence/display/CASSANDRA/4.0+Quality%3A+Components+and+Test+Plans
In parallel we have begun performance testing 4.0 and have already seen order
of magnitude improvements of cluster startup times, streaming data to new
nodes and internode messaging. This has been the direct result of a re-write
of the internode communication layer to rely on NIO via the Netty API. These
improvements have been tracked on the following parent issue:
https://issues.apache.org/jira/browse/CASSANDRA-14746
## PMC changes:
We have added four new PMC members during this period. There are currently 31
PMC members.
- New PMC members:
- Ariel Weisberg was added to the PMC on Tue Sep 25 2018
- Benedict Elliott Smith was added to the PMC on Tue Sep 25 2018

## Committer base changes:
There are currently 50 committers. No new committers added in the last 3
months.
## Releases:
The last release was 2.2.13 on Wed Aug 01 2018.
## Mailing list activity:
We have had a substantial uptick in traffic on the development mailing list as
a result of robust discussions around a feature freeze for 4.0, calls for
participation for testing 4.0, and inclusion of a side-car management process
for repair.

## Description: The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data. Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages. ## Issues: There are no issues requiring board attention at this time. ## Activity: We have spent this quarter working on preparations for getting the community involved and excited about the upcoming release of 4.0. This effort includes: - Agreeing upon the timeline for a feature freeze - Updating our site to add a blog section with our first community submitted blog - Adding a Confluence space to track testing progress towards 4.0 In other news, we filed CVE-2018-8016 for a regression vulnerability. Fortunately this had already been fixed in the latest release by the time the issue was identified and the CVE created. ## PMC changes: - There are currently 27 PMC members. - Benjamin Lerer was voted onto the PMC. If no objections from the board are received, he will be invited to join shortly. - Last PMC addition was Sam Tunnicliffe on Tue Apr 03 2018 ## Committer base changes: - There are Currently 50 committers. - No new committers have been added in the last 3 months - The last committer addition was Jay Zhuang on 2018-02-27 ## Releases: We recently had three releases across the following versions - 2.2.13 was released on Wed Aug 01 2018 - 3.0.17 was released on Wed Aug 01 2018 - 3.11.3 was released on Wed Aug 01 2018 ## Mailing list activity: Mail list activity is down from the previous quarter. We see this as a function having no new major releases in conjunction with a focus on getting 4.0 ready to freeze. Mail list interactions remain healthy with a core group of contributors answering questions. dev@cassandra.apache.org: - 1628 subscribers (up 2 in the last 3 months): - 306 emails sent to list (671 in previous quarter) user@cassandra.apache.org: - 3060 subscribers (up 1 in the last 3 months): - 910 emails sent to list (1406 in previous quarter) ## JIRA activity: - 185 JIRA tickets created in the last 3 months - 132 JIRA tickets closed/resolved in the last 3 months

Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages. ## Issues: There are no issues requiring board attention at this time. ## Activity: After several lengthy mail list discussions, a consensus reached on the timeframe of early September for creating a 4.0 branch and what the rough goals are going to be for a feature set. This consensus has been in the making for some time, so we are glad to have it. ## Health report: As seen from the mail list activity and committer and PMC additions, overall the project is healthy. ## PMC changes: There are currently 27 PMC members. Three New PMC members were added during this reporting period: - Blake Eggleston on Wed Mar 28 2018 - Sam Tunnicliffe on Tue Apr 03 2018 - Stefan Podkowinski on Wed Mar 07 2018 ## Committer base changes: There are currently 50 committers. One committer was added during this reporting period: - Jay Zhuang on Wed Feb 28 2018 ## Releases: We had a minor release on each of our four supported branches: - 2.1.20 was released on Fri Feb 16 2018 - 2.2.12 was released on Fri Feb 16 2018 - 3.0.16 was released on Mon Feb 19 2018 - 3.11.2 was released on Mon Feb 19 2018 ## Mailing list activity: Mail list activity on the dev and user lists has been up substantially. We attribute the rise in dev list activity to a series of robust discussions regarding the timeline of branching and releasing a forthcoming 4.0. dev@cassandra.apache.org: - 1626 subscribers (down -4 in the last 3 months): - 703 emails sent to list (180 in previous quarter) user@cassandra.apache.org: - 3060 subscribers (down -35 in the last 3 months): - 1487 emails sent to list (721 in previous quarter) ## JIRA activity: - 230 JIRA tickets created in the last 3 months - 190 JIRA tickets closed/resolved in the last 3 months

This should pay off quickly in an faster development cycle for fixing more nuanced issues common in a distributed database. We received a vulnerability report this quarter that was more a mis-understanding of how internode communication and security works with a default installation. The only action needed was an update of our documentation with specific details on mitigating this issue through correct setup of security configuration options. We continue to maintain four active branches as well as working towards our eventual goal of releasing 4.0. Though the changelog for this next version is becoming quite long, we are not under any pressure from external vendors and are therefore taking "as long as is needed" to release something stable that committers and contributors are comfortable running in production (and thus comfortable recommending such to users). Given our project's track record of "it's not stable until X.X.6," we feel strongly that this is the correct approach. ## Health report: Overall the project is healthy. We've seen several new contributors recently working on core components such as compaction and storage. ## PMC changes: There are currently 24 PMC members. No new PMC members have been added in the last 3 months. The last PMC addition was Jon Haddad on Sun Aug 20 2017 ## Committer base changes: There are currently 47 committers. No new committers have been added in the last 3 months. The last committer addition was Jon Haddad at Sat Aug 19 2017. ## Releases: The last release was 3.0.15 on Tue Oct 10 2017. However, we just opened a vote on releasing bug fixes across the following active branches: 2.1.20, 2.2.12, 3.0.16, and 3.11.2. ## Mailing list activity: Subscriptions for dev@ have gone up, potentially reflecting more participation from newer contributors. We attribute the downward trend in messages sent to the holiday period this quarter. dev@cassandra.apache.org: - 1630 subscribers (up 6 in the last 3 months): - 189 emails sent to list (340 in previous quarter) pr@cassandra.apache.org: - 10 subscribers (up 0 in the last 3 months): - 149 emails sent to list (110 in previous quarter) user@cassandra.apache.org: - 3093 subscribers (down -11 in the last 3 months): - 894 emails sent to list (1109 in previous quarter) ## JIRA activity: - 218 JIRA tickets created in the last 3 months - 134 JIRA tickets closed/resolved in the last 3 months

This conference was planned and run solely by the community coordinated on the private, development and user mail lists (as appropriate) with no vendor influence. Talks were selected directly by the PMC. A summary of the event posted to the dev list can be found here: https://lists.apache.org/thread.html/5ab801e508a792d81defe092a77c59df862ce36b1 4c1a41445367190@%3Cdev.cassandra.apache.org%3E Great care was taken to summarize any major discussions back to their respective JIRA tickets as well as summarize and continue conversations on the development mailing list after the event to facilitate larger community participation. A huge thanks to long-time PMC members Gary Dusbabek and Eric Evans for doing all the leg work in putting this event on. ## Health report: Overall the project is healthy. We continue to leverage the lack of any vendor influence by focusing the current work on stability and testing. ## PMC changes: There were three new PMC members added this quarter: - Josh McKenzie was added to the PMC on Fri Aug 18 2017 - Marcus Eriksson was added to the PMC on Fri Aug 18 2017 - Jon Haddad was added to the PMC on Sun Aug 20 2017 ## Committer base changes: There was one committer added this quarter: - Jon Haddad was added as a committer on Sat Aug 19 2017 ## Releases: - 2.1.19 was released on Thu Oct 05 2017 - 2.2.11 was released on Thu Oct 05 2017 - 3.0.15 was released on Tue Oct 10 2017 - 3.11.1 was released on Tue Oct 10 2017 ## Mailing list activity: Development list activity saw a substantial uptick as the result of continuation of discussion from topics presented at the NGCC. User list activity remained stable. dev@cassandra.apache.org: - 1626 subscribers (up 5 in the last 3 months): - 349 emails sent to list (316 in previous quarter) user@cassandra.apache.org: - 3102 subscribers (down -6 in the last 3 months): - 1150 emails sent to list (1133 in previous quarter) ## JIRA activity: - 249 JIRA tickets created in the last 3 months - 211 JIRA tickets closed/resolved in the last 3 months

It's been about a year since the inquiry from the board and we've continued to make progress expanding the committer base and PMC membership while moving forward with development. We very much appreciate the involvement of the management, membership and community with the resolution of LEGAL-303. The paves the way for a first implementation of new functionality around pluggable storage engines. The cassandra-dtest project made it through the ASF code donation process. This has removed a small bottleneck and source of occasional test errors by allowing committers to commit distributed test suites at the same as code commits to the core project. ## PMC changes: There are currently 21 PMC members. No new PMC members added in the last 3 months. The last PMC addition was Sankalp Kohli on Mon Oct 24 2016. Note that there are currently open votes for four additional PMC members. They should be resolved by the time the board meets. ## Committer base changes: There are currently 46 committers. Philip Thompson was added as a committer on Fri Jun 23 2017. ## Releases: The final release of the 2.1.x series was done this quarter. Maintenance releases were done on the 2.2.x, 3.0.x, 3.11.x branches. We anticipate a release of 4.0 in the next quarter. - 2.1.18 was released on Mon Jun 26 2017 - 2.2.10 was released on Mon Jun 26 2017 - 3.0.14 was released on Fri Jun 23 2017 - 3.11.0 was released on Fri Jun 23 2017 ## Mailing list activity: The participation on the dev list was down this quarter, perhaps attributed to summer holidays and the lack of anything contentious. However, user list participation was up slightly which is a good sign of positive community engagement. dev@cassandra.apache.org: - 1625 subscribers (down -2 in the last 3 months): - 320 emails sent to list (474 in previous quarter) user@cassandra.apache.org: - 3112 subscribers (down -18 in the last 3 months): - 1112 emails sent to list (1107 in previous quarter) ## JIRA activity: - 230 JIRA tickets created in the last 3 months - 156 JIRA tickets closed/resolved in the last 3 months

We have added additional avenues of test resource integration (specifically providing base Travis and CircleCI configurations in tree) for any member in the community to take advantage of for their personal development branches. Note that ASF Jenkins is still used exclusively for committed code. The benefits of this have been a wider participation from newer community members, as we are taking advantage of "free" resources for open source projects offered by those companies for day to day development. Overall, we have increased our velocity over the past quarter and are closing tickets a faster pace than the previous two quarters. ## Issues: There are no new issues requiring board attention at this time. ## Releases: Apache Cassandra has had the following releases: - 2.1.17 was released on Mon Feb 20 2017 - 2.2.9 was released on Mon Feb 20 2017 - 3.0.11 was released on Mon Feb 20 2017 - 3.0.12 was released on Thu Mar 09 2017 - 3.0.13 was released on Thu Apr 13 2017 ## PMC changes: Currently 21 PMC members. No new PMC members added in the last 3 months. ## Committer base changes: Five new committers have been added in the past quarter: - Ariel Weisberg was added as a committer on Mon Feb 13 2017 - Blake Eggleston was added as a committer on Mon Feb 13 2017 - Alex Petrov was added as a committer on Mon Feb 13 2017 - Joel Knighton was added as a committer on Tue Feb 14 2017 - Stefan Podkowinski was added as a committer on Sat Feb 18 2017 ## Mailing list activity: Subscriptions to the user list are off slightly but the number of messages has increased. This could be a result of efforts to make unsubscribing from the mail list a little easier. Dev list activity is down compared to the previous quarter but still healthy. Note that the previous quarter can be considered an outlier given the volume of messages during discussions of changing the release process. dev@cassandra.apache.org: - 1615 subscribers (up 0 in the last 3 months): - 515 emails sent to list (560 in previous quarter) user@cassandra.apache.org: - 3132 subscribers (down -10 in the last 3 months): - 1153 emails sent to list (1115 in previous quarter) ## JIRA activity: As mentioned above, the number of closed/resolved tickets has increased almost 30% over the previous quarter. - 316 JIRA tickets created in the last 3 months - 259 JIRA tickets closed/resolved in the last 3 months
## Description: Since the last report, things have stabilized a bit in the community and we are getting down to business. After several long conversations on the dev list, we have agreed on the best way forward of streamlining our release process. Specifically, we have moved away from the TicTock scheme used throughout the 3.x releases. Though it had the benefit of creating a better culture of testing, this process proved to be both incredibly confusing for users as to the current stable version and overly difficult to maintain for developers for the number of active branches required. Our development velocity is lower than I would like. We are still recovering from the pull out of a large commercial vendor in the space, but independent activity is increasing and we are steadily adding committers. It took five voting rounds to release 3.10, but that is more a function of our agreement to insist on a green test board and being more stringent on blocking for known issues. I see this particularly as a positive sign of higher community involvement in the development process as three of the vote vetoes were a result of end-user discovered issues. ## Issues: There are no new issues requiring board attention at this time. ## Release Activity: Apache Cassandra has had the following releases: - 3.0.10 was released on Wed Nov 16 2016 - 3.10 was released on Fri Feb 03 2017 We are currently working towards an alpha of 4.0 that is a cleanup and refactoring of some major components. ## PMC changes: Currently 21 PMC members. No new PMC members added in the last 3 months. ## Committer base changes: Three new committers have been added in the past quarter: - Branimir Lambov was added as a committer on Tue Nov 08 2016 - Paulo Motta was added as a committer on Wed Dec 07 2016 - Stefan Powkowinski was voted in, but is pending an ICLA review by his employer ## Mailing list activity: Subscriber increases on both mailing lists are marginal, but they are increases. Activity on the user mailing list is down, but we see that as a function of not having any new releases before and during the holiday period. dev@cassandra.apache.org: - 1613 subscribers (up 28 in the last 3 months): - 573 emails sent to list (611 in previous quarter) user@cassandra.apache.org: - 3135 subscribers (up 30 in the last 3 months): - 1142 emails sent to list (1548 in previous quarter) ## JIRA activity: The ratio of closed to created tickets is high, reflective of previous comments regarding velocity. - 302 JIRA tickets created in the last 3 months - 190 JIRA tickets closed/resolved in the last 3 months
@Shane: please explain the comment regarding external org
## Description:
The past couple of months have been difficult for us. For posterity, the
August [0] and September[1] board agendas provide details of changes
affecting the project and subsequent PMC efforts to address board requested
action items. We will continue to work constructively with the board on the
points therein.
With that said, we would like to express not only our optimism (more below)
but our thanks to those within the ASF who have spent substantial amounts of
time to help us get moving in the right direction. Of particular note have
been the ongoing efforts Mark Thomas and Jake Farrell. Without them, it would
have been much more difficult to deduce what to do next and how to go about
doing it. For everyone else, a large thank you as well. If nothing else, it's
clear we all care very deeply about having successful open source software
projects.
## Issues:
A long-time vendor who has been a large benefactor of the project through
contribution of resources, has re-focused said resources to more internal
efforts[2]. While many of their staff are still involved in day-to-day
activities, it has left something of a hole for the PMC to fill in terms of
handling day-to-day resourcing of issues.
Discussions are ongoing on how best to do this, but we remain optimistic that
the size, diversity and skill of the community are enough that we will find
solutions.
## Release Activity:
Apache Cassandra has had the following releases:
- 2.1.16 was released on Mon Oct 10 2016
- 2.2.8 was released on Wed Sep 28 2016
- 3.8 was released on Thu Sep 29 2016
- 3.9 was released on Thu Sep 29 2016
We have recently moved trunk up to 4.0 and are currently discussing a roadmap
for such on the development mailing list.
Note: 3.10 and 3.0.10 were scheduled to be released, but were voted down due
to a regression bug discovered by the community.
## Health report:
From the past several weeks of mailing list and social media activity, one
can draw the following conclusions regarding the health of Cassandra:
- our large, diverse community of users care deeply about the project and are
not afraid to very publicly ask hard questions
- the board cares deeply about our project as can be seen by amount of effort
expended in handling not only Cassandra but the larger issues brought about
by the point above
- the PMC wants very much to do the right thing and is doing its best to
constructively move forward
In short, we do not lack for passion at any level of the project. It is
therefore our game to lose and we intend to put our best efforts in over the
next quarter.
## PMC changes:
- Currently 21 PMC members.
- There are two new PMC members:
- Sankalp Kohli was added to the PMC on Mon Oct 24 2016
- Michael Shuler was added to the PMC on Thu Sep 22 2016
## Committer base changes:
- Currently 38 committers.
- There are three new commmitters:
- Dikang Gu was added as a committer on Fri Nov 04 2016
- Sankalp Kohli was added as a committer on Tue Oct 25 2016
- Branimir Lambov was voted in and accepted, we are awaiting ICLA
submission
## Mailing list activity:
Activity on both dev and user mail lists have increased substantially over
last quarter. We have no direct quantitative information as to why, but
anecdotally it appears that we have knowledgeable users appearing more
often to answer other users's questions.
- dev@cassandra.apache.org:
- 1582 subscribers (down -3 in the last 3 months):
- 709 emails sent to list (452 in previous quarter)
- Though not as high and some is resulting to larger political
discussions, we still have over 60% growth in traffic.
- user@cassandra.apache.org:
- 3109 subscribers (down -6 in the last 3 months):
- 1597 emails sent to list (901 in previous quarter)
- Mail list activity has increased over 50% from the last quarter.
## JIRA activity:
As discussed above in Issues we would like the number of resolved issues
to be higher, but over 75% is not a bad place to be and we are actively
working on getting more community involvement.
- 480 JIRA tickets created in the last 3 months
- 372 JIRA tickets closed/resolved in the last 3 months
## Trademark Enforcement
Three requests were sent out regarding our trademarks, all of which were
immediately complied with by the recipients:
- Clarified appropriate use of trademark and guidelines for a third party
vendor providing backports of Apache Cassandra patches to a custom long
term release version [3]
- Use of trademark in project name [4]
- Use of trademark in project name [5]
## 'dtest' Project Contribution
DataStax recently offered to donate the dtest distributed testing suite to
the project [6],[7]. This was voted on in the dev mailing list and passed
[8]. Filing the appropriate forms with the Incubator folks for review will be
done shortly.

## Description:
- This report is was created in response to a request from Mark Thomas on
behalf of the ASF board. This request listed 10 specific action items to be
undertaken by the PMC including the creation of this report outside of the
project's normal reporting cycle. The content of the original email has
been added to the PMC's svn repository and was used as a checklist [0] to
organize PMC efforts in addressing these action items.
- This report includes a "Board Requested Actions" section which provides a
summary of said actions followed by specific activity undertaken by the PMC
for each.
## Board Requested Actions
- Review of Apache trademark policy by PMC members
The following PMC members have signed off as having reviewed ASF
trademark policy:
amorton
dbrosius
eevans
gdusbabek
jake
jasobrown
jbellis
jfarrell
jjirsa
slebresne
tylerhobbs
zznate
- Review DataStax controlled web properties for clear separation between
DataStax and Cassandra
DataStax web properties were reviewed and several small issues identified.
An email was sent on by Nate McCall on behalf of the PMC to Christian Hasker
(identified by Jonathan Ellis for the DataStax point of contact) requesting
that they be addressed. Christian replied twice indicating that they were
taking immediate action and to later update on progress. A correspondence
email [1] has been uploaded.
- Review project controlled web properties for clear separation between
DataStax and Cassandra
The remaining references to DataStax on the project's web properties
are under the Documentation section and take one of two forms:
- links to contextually relevant blog posts under datastax.com
- references to client driver projects
- Review release artifacts and documentation for clear separation between
DataStax and Cassandra
The project's downloads page lists ASF Debian packages as official binaries.
Binaries managed by DataStax have been moved towards the bottom stating
explicitly that they are not endorsed.
- Identify a process for ongoing monitoring of the projects marks
The PMC has not yet discussed a process for monitoring the projects marks.
- Ensure the Cassandra Summit follows the ASF guidelines for events
Jake Luciani reached out to the organizers on behalf of the PMC and uploaded
correspondence emails [2] with conference organizer who addressed/documented
the points raised. The document includes email threads of ASF channels used
for trademark and cfp requests.
- Replacement for Jonathan after stepping down as chair
The following three PMC members were nominated: Eric Evans, Jake Luciani,
Nate McCall.
Nate McCall was voted as successor and was put forward to the board.
- Review DataStax's "Cassandra MVP" program for a clear separation between
DataStax and Cassandra
A review of current DataStax content for the MVP program (including this
year's Cassandra Summit) shows the primary wording is now "DataStax MVP for
Apache Cassandra." There are, however, two older community-contributed posts
on the Planet Cassandra property that use the phrase "DataStax Cassandra
MVP."
- Stop using non-ASF, non-archived back channels for discussion
The project is now using ASFBot for logging the #cassandra-dev [3] IRC
conversations.

Sixty committers and contributors attended. Day 1 saw presentations from engineers from Apple, DataStax, Eriksson, Instagram, The Last Pickle, Protectwise, Stratio, and Yahoo Japan. These presentations were followed on Day 2 by an unconference discussion. My notes are here [1] and videos are here [2]. O’Reilly’s Cassandra: The Definitive Guide 2nd Edition [3] is out. This is the first book to cover Cassandra 3.0. PMC & Committers ---------------- Jeff Jirsa was added as committer on 15 Jun 2016. Dave Brosius, Tyler Hobbs, and Aaron Morton were added as PMC members on 10 Jun 2016. 1 committer and 5 PMC member votes are currently in progress.

The Board expressed continuing concern that the PMC was not acting independently and that one company had undue influence over the project.
PMC representatives acknowleged the Board's concerns and asked for clarity from the Board in the form of explicit actions that the PMC should be taking to improve the situation.
It was suggested that a representative from the board could meet with senior company management to relate the board's concerns directly.
It was agreed that the project should report again next month.
@Mark: Summarize items for PMC to address
@Jim: Arrange a meeting to relate the Board's concerns with senior company management.
Cassandra is a distributed database providing massive scalability, high performance, and high availability. Releases: 3.6 13 May 2016 (Expected) 3.0.6 13 May 2016 (Expected) 2.2.6 26 Apr 2016 2.1.14 26 Apr 2016 3.5 13 Apr 2016 3.0.5 11 Apr 2016 3.4 8 Mar 2016 3.0.4 8 Mar 2016 Development: Cassandra has moved to a monthly release schedule, with even releases (3.4) including new features, and odd releases (3.5) only bug fixes. 3.4 includes the new SASI feature (SSTable-Attached Secondary Indexes). Unlike Cassandra's older indexes, SASI are btree-based, allowing range scans and full-text indexing. 3.6, whose vote is in progress as of this writing, adds support for much larger partitions, which makes it easier to build Cassandra data models where the "natural" partitioning would generate millions of rows per partition. Community: The NGCC (Next Generation Cassandra Conference), for Cassandra committers and contributors, was moved to June to avoid conflict with ApacheCon NA. ApacheCon saw five talks on Cassandra from five different companies, anchoring the NoSQL category. Cassandra passed MS Access to take the #7 spot on DB-Engines' database popularity ranking [1]. Of course, the two systems are not remotely comparable, but this is a positive sign for adoption. Committers Yuki Morishita and Jake Luciani have experimented with teaching workshops on contributing to Apache Cassandra at two different companies in an effort to accellerate the pool of contributors and committers. So far, this has resulted in some small patches from engineers at Yahoo Japan; we hope to see more from them soon. Kaide Mu's proposal to add an sstable downgrade tool was accepted for Google Summer of Code, under mentors Paulo Motta and Yuki Morishita.

A good summary of what's new in 3.2 is at [2]. Community: Pretty quiet start to the year. I am in the initial stages of planning NGCC (Next Generation Cassandra Conference, for Cassandra committers and contributors, not end users) 2016, probably for late April.

[1] Headlining features include a CQL-based storage engine (blog post forthcoming), materialized views [2], and optimzied hint storage [3]. Community: The 2015 Cassandra Summit in San Francisco was September 22-24. For the first time, this was a two day conference, and attracted over 3,200 attendees. I believe this makes it the largest NoSQL conference in the world. Open Source Connections has a good writeup at [4].

Cassandra is a distributed database providing massive scalability, high performance, and high availability. Releases: 2.2.0 20 Jul 2015 2.2rc2 9 Jul 2015 2.1.8 9 Jul 2015 2.1.7 22 Jun 2015 2.0.16 22 Jun 2015 2.2rc1 8 Jun 2015 2.1.6 8 Jun 2015 2.2b1 19 May 2015 Development: With most of Cassandra 3.0 development complete, but with release stalled by continuing difficulties in finishing CASSANDRA-8099 (a rewrite of the storage engine around CQL principles rather than the old Thrift API), we decided to release the-features-formerly-known- as-3.0 as 2.2 as soon as possible, followed by a 3.0 release later based on 8099. 2.2 has now been released successfully. I summarized the new features in [1]. Community: Gearing up for the 2015 Cassandra Summit in San Francisco, September 22-24. For the first time, this will be a two-day cconference, plua a day of hands-on training. Most recent committer and PMC changes: Sam Tunnicliffe was added as committer on 18 May 2015. Aleksey Yeshchenko was added as PMC member on 7 Aug 2014. [1] http://www.datastax.com/dev/blog/cassandra-2-2
Cassandra is a distributed database providing massive scalability, high performance, and high availability. Releases: 2.0.15 29 Apr 2015 2.1.4 1 Apr 2015 2.0.14 1 Apr 2015 2.1.3 16 Mar 2015 Development: A security issue was reported to Apache that Cassandra's default configuration allowed arbitrary code to be executed remotely via JMX. We followed Apache protocol and developed a fix as a PMC (led by Eric Evans and Jake Luciani) resulting in the 2.0.14 and 2.1.4 releases prior to the public announcement of the vulnerability [1]. With most of Cassandra 3.0 development complete, but with release stalled by continuing difficulties in finishing CASSANDRA-8099 (a rewrite of the storage engine around CQL principles rather than the old Thrift API), we decided to release the-features-formerly-known- as-3.0 as 2.2 as soon as possible, followed by a 3.0 release later based on 8099. I expect a vote to begin on 2.2 beta 1 by the time the board meets. Community: We had our second annual Next Generation Cassandra Conference for Cassandra developers. (I.e., much smaller than a user-oriented conference.) We had just over 50 developers attend this year in Austin in conjunction with ApacheCon. Speakers included committers and contributors from Apple, DataStax, Mesosphere, SVDS, and Vast. Tokyo Cassandra Summit saw 500 registrations for the April event [2], about double last year's. This puts it about on par with our San Francisco summit from 2011, although the two events are not directly comparable. (San Fransisco charged a fee to attendees, while Tokyo's cost was borne entirely by sponsors, in large part because Tokyo was able to find a sponsor willing to provide the venue for free.) As you know, it is often difficult for Western open source projects to gain traction in Japan (and vice versa) because of the language barrier, so I am glad to see this growth. One analyst who attended commented to me that he found it notable that by his estimate, about 40% of the audience at the Tokyo Summit were businessmen, compared to virtually none at the MongoDB event that he attended recently. He interpreted this to mean that Cassandra is more interesting to the enterprise market that makes up so much of the Japanese industry. Most recent committer and PMC changes: Robert Stupp was added as committer on 15 Jan 2015.* Aleksey Yeshchenko was added as PMC member on 7 Aug 2014. *Sam Tunnicliffe has been voted in as committer, but has not submitted his ICLA as of this writing.

Cassandra is a distributed database providing massive scalability, high performance, and high availability. Releases: 2.0.12 20 Jan 2015 2.1.3 17 Feb 2015 Development: Cassandra developers are working on delivering 3.0 in the first half of 2015, with user-defined functions [1], JSON support [2], disk-aware vnodes [3], role-based access control [4], specialized hint storage [5], global indexes [6], and Windows support. Community: Cassandra Day Los Angeles was a free, four-track conference that drew about 600 attendees. [7] (The linked article says 1,000 registered; 40% did not show up, which is typical for free events.) The next Cassandra Day (19 March) will be done in Atlanta by the time the board meets.

Counters have been rewritten [5], and compaction has been tuned to be page-cache-aware [6]. Community: September saw 1,800 Cassandra users (and another 1,000 online) attend the 2014 Cassandra Summit in San Francisco. This represents a sold out venue, up from the 1,100 from 2013.

Cassandra is a distributed database providing massive scalability, high performance, and high availability. Releases: 2.0.8 29 May 2014 2.0.9 30 Jun 2014 1.2.17 30 Jun 2014 1.2.18 3 Jul 2014 2.1 rc1..rc6 May-Aug 2014 Development: 2.1 is feature complete with optimized repair [1] and off-heap memtables [2] joining user-defined types [3] and collection indexing [4]. Counters have been rewritten [5], and compaction has been tuned to be page-cache-aware [6]. We have required more release candidates than expected. I believe that this is due to increased efforts around QA rather than worse code quality than previous releases. Community: Joshua McKenzie was added as committer on 29 Jul 2014. Aleksey Yeshchenko was added as PMC member on August 7 2014. P.S.: I apologize for the late report.

User-defined types [1] and collection indexing [2] are complete, and internal optimization is ongoing: we have added a persistent, atomic b-tree that saves 60% heap space compared to SnapTreeMap [3]. Community: The January 2014 Cassandra Summit Japan [4] [5] saw about 100 attendees, a small increase over December 2012. About 2/3 of the audience were running Cassandra in production. There was widespread agreement that the English language is the largest barrier to Cassandra use in Japan, and growth will not take off until Japanese documentation is available.

Lightweight transactions are a first for a system built on eventual consistency, and allows opting in to linearizable consistency when necessary, giving users the best of both worlds [1]. 2. We're dropping a lot of legacy baggage (but not API compatibility), requiring users to upgrade through 1.2 first if they are on an earlier release [2]. Community: The 2013 Cassandra Summit was a two-day event for the first time and saw over 1,100 attendees in SF [3]. Jake Luciani was added to the PMC on August 12.

Besides those based in the Bay area, several committers flew in from out of town. Aleksey Yeschenko and Jake Luciani attended remotely via Google Hangout. General sentiment was that the meeting was a success, but we will try our next meeting entirely virtually over Hangout, both to reduce the travel overhead and to make everyone more of an equal participant.

Cassandra is a distributed database combining the best of Google's Bigtable and Amazon's Dynamo. --Highlights-- Cassandra NYC [1] was a full-day, two track conference that drew about 150 attendees. [1] http://www.datastax.com/events/cassandranyc2011 --Releases-- 0.8.8, 0.8.9, 1.0.3, 1.0.4, 1.0.5, 1.0.6, 1.0.7 --Community-- Added committers Vijay Parthasarathy from Netflix, and Aaron Morton, an independent consultant.
Cassandra is a distributed database combining the best of Google's Bigtable and Amazon's Dynamo. --Highlights-- Releasing 1.0.0 was a big deal [1] [2]. We added the overwhelmingly most popular feature request (compression) and addressed some long-standing weaknesses in the storage engine. We also continued our efforts to make Cassandra more accessible to mainstream developers and ops teams.

This is not perfect, but it's progress. The 1.0.0 feature freeze period also more participation than we've seen before, particularly from the Rakuten and Gemini teams in Japan. 1.0.0 was easily our most solid .0 release yet. Still, most teams wait for the final release before testing in earnest. --Community-- To celebrate 1.0.0, I offered a "Cassandra Bug Hunter" shirt to everyone who has contributed one or more patches to Cassandra (we track these as "contributors" in Jira). There were 189.
Cassandra is a distributed database combining the best of Google's Bigtable and Amazon's Dynamo. --Highlights-- The Cassandra SF 2011 conference was a resounding success. We reached the venue's capacity and had to cap attendance at about 450, over twice last year's attendance. We were also able to increase from two tracks of talks, to three. After 0.7, Cassandra switched to a time-based release process. 0.8.0 was the first release under this system and was our most stable .0 release yet. We consider the change a success and plan to release 1.0 under a similar plan in October. --Releases-- 0.7.6, 0.7.7, 0.7.8, 0.8.0, 0.8.1, 0.8.2 0.6 has been put out to pasture. There have been no new bug reports and we do not anticipate any releases after April's 0.6.13. --Community-- Added Pavel Yaskevich as committer.
Cassandra is a distributed database combining the best of Google's Bigtable and Amazon's Dynamo. --Highlights-- After a prolonged 0.7 release with a lot of feature creep, Cassandra has switched to a time-based release for 0.8 and expect to have it out by the end of May. Notable features include counter support and CQL, an SQL-based query language with extensions for Cassandra's sparse-row data model. --Releases-- 0.6.12, 0.6.13, 0.7.1, 0.7.2, 0.7.3, 0.7.4, 0.7.5, 0.8b1, 0.8b2 --Community-- Added Sylvain Lebresne as committer.
Roy is impressed that with nine releases this quarter, they are still unsatisfied by "long feature creep".
Cassandra is a distributed database combining the best of Google's Bigtable and Amazon's Dynamo. --Highlights-- Several Cassandra deployments have gotten positive press recently, including Netflix, Openwave, and Twitter's Rainbird. 0.7.0 was released with many new features, including index queries against column values. --Releases-- 0.6.9, 0.6.10, 0.6.11, 0.7.0 --Community-- Added Jake Luciani as committer.
Cassandra is a distributed database combining the best of Google's Bigtable and Amazon's Dynamo. --Highlights-- The ApacheCon Cassandra/NoSQL track went extremely well, with great talks that often saw standing-room-only attendance. The Cassandra meetup at ApacheCon also saw a good turnout. Cassandra got a lot of positive attention recently when Digital Reasoning announced that the US Government has a 400 node Cassandra cluster. --Releases-- 0.6.5, 0.6.7, 0.6.8 0.7-beta2, 0.7-beta3 0.7-final is taking longer than expected, primarily because of some corner cases of the new schema modification code. While we work out those last details, we've branched 0.7 so work on new features for the next major release can proceed in parallel. --Community-- Cassandra has been getting a lot of positive attention at conferences, including JavaOne, CME, Oredev, Devoxx, and NoSQL Japan, as well as ApacheCon. We have no new committers since the last board report, but we do see a long tail distribution of contributions from the community -- we recently passed the 100-person mark of contributors who have had at least one patch accepted. With luck we will be able to help some of these move towards becoming a full committer.
Cassandra is a distributed database similar to Google's Bigtable or Amazon's Dynamo. --Highlights-- The first Cassandra Summit was held in San Francisco on August 10 with almost 200 attendees. The 0.7 release is coming along nicely, with a large amount of new features and performance improvements. --Releases-- 0.6.1, 0.6.2, 0.6.3, 0.6.4 0.7-beta1 --Community-- Gary Dusbabek has been added to the PMC. Brandon Williams was added as committer.

Cassandra is a distributed storage system providing reliability at a massive scale. Started incubation: 01/2009. Opened to community in 03/2009. The original authors of Cassandra from facebook (Avinash and Prashant) have gone back to developing against an internal repository. We have never seen any involvement from initial committer Dan, either. Despite this setback we continue to make progress; a 0.3.0 release is imminent and two more committers have been nominated, out of six who regularly submit patches. Cassandra was represented at the recent NoSQL distributed database summit by Avinash and Jonathan and was very well received. Past action items: * Consensus about the development process. Done. Development is done in trunk with branches for releases. A pre-commit patch review process is followed that will be familiar to most apache committers. * JIRA permissions and configuration. Done. * A bit more information on the web site. Done. Next steps: * Get new committers voted on * Get 0.3.0 release out
Cassandra is a distributed storage system for managing (un)structured data while providing reliability at a massive scale. It has been in incubation since January 2009. The incubator project had a very slow start. Code started to get moved over from Google Code just about 5 weeks ago. But a very basic web site and the wiki is in place. A new committer was elected. Unfortunately there is some friction about contributions, code reviews and branching that needs to be addressed ASAP. This is a community issue and we hope to get this resolved. More on that in the next report. * Consensus about the development process (code reviews, branching etc) * JIRA permissions and configuration * A bit more information on the web site = Empire-db = Empire-db is a relational data persistence component that aims to overcome the difficulties, pitfalls and restrictions inherent in traditional Object Relational Management (ORM) approaches. Empire-db is on the Apache Incubator since July 2008. Community: * Development seems to pick up some momentum. Parts of the code are now unit-tested and two new integration examples have been added (Apache CXF) * dev@ and user@ traffic is rising, this brought some fixes to PostgreSQL Driver as well as some possible changes for future releases. Release: * Preparations for a release are under way, this will be our first maven-based release * We hope the switch to maven will lower the barrier for adoption Issues prior to graduation: * Grow the community, * Successful maven-based release * Even more integration example code (Apache Wicket?) + more documentation
Cassandra failed to report. They did recognize and discuss the need for a report, but failed to provide one, anyway. The Cassandra Project is a distributed storage system for managing structured/unstructured data while providing reliability at a massive scale.
