## Description: The mission of BookKeeper is the creation and maintenance of software related to Replicated log service which can be used to build replicated state machines ## Issues: Overall the community is doing well. On the PMC side we can note that we had a CVE and it took much time in order to handle it properly. This is something that we are still not tackling on the PMC. There are a few contributors who are doing very well and it is probably worth considering inviting them as committers. ## Membership Data: Apache BookKeeper was founded 2014-11-19 (8 years ago) There are currently 30 committers and 17 PMC members in this project. The Committer-to-PMC ratio is roughly 8:5. Community changes, past quarter: - No new PMC members. Last addition was Andrey Yegorov on 2022-03-18. - No new committers.

We are going to cut a new major release (4.16.0) ## Community Health: The community is active, in mailing list discussion, on our slack workspace, on GH pull requests and BPs (BookKeeper proposals, that is our way of discussing public API changes and big features)
## Description: The mission of BookKeeper is the creation and maintenance of software related to Replicated log service which can be used to build replicated state machines ## Issues: The community is pretty healthy currently, new features and bugfixes are coming both from committers and new contributors and we recently added some committers. One issue is that we missed to send the report to the Board a couple of times, and also sometimes it takes much time to have 3 binding VOTEs on release candidetes. Maybe it is time to add new members to the PMC or to revive the PMC. A CVE has been found (https://www.cve.org/CVERecord?id=CVE-2022-32531) and it took much time before we could address it, ## Membership Data: Apache BookKeeper was founded 2014-11-19 (8 years ago) There are currently 30 committers and 17 PMC members in this project.

The activity on the ML is stable on dev@, and we are also following a formal process to get major changes in (BookKeeper Proposals design documents). We had a BookKeeper dedicated track at PulsarSummit.com, a conference devoted to Apache Pulsar. We also have a few talks about BookKeeper at ApacheCon@Home. We recently moved to GitHub Actions the CI jobs relevant to testing Pull Requests.
## Description: BookKeeper is a scalable, fault-tolerant, and low-latency storage service optimized for append-only workloads. It has been used as a fundamental service to build high available and replicated services. It is also the log segment store for Apache DistributedLog and message store for Apache Pulsar. Apache DistributedLog is a high-level API and service layer for Apache BookKeeper, providing easier access to the BookKeeper primitives. It is a subproject of Apache BookKeeper. ## Issues: There are no issues requiring board attention at this time. ## Membership Data: Apache BookKeeper was founded 2014-11-19 (5 years ago) There are currently 23 committers and 16 PMC members in this project. The Committer-to-PMC ratio is roughly 3:2. Community changes, past quarter: - No new PMC members. - Rajan Dhabalia was added as committer on 2020-03-23 ## Project Activity: Recently, we've seen lots of activity from upstream consumers such as Apache Pulsar. Companies such as Salesforce and Diennea contributing back to the community. We are also seeing new interest from users at Dell EMC contributing back and starting conversations. Several bugs (issues) were opened and fixed from these upstream consumers which will be going into our next release. Some of the important features being worked on/recently merged are: - Bookkeeper Proposal - 38: Publish Bookie Service Info on Metadata Service - Bookkeeper Proposal - 40: Audit Logging for Apache Bookkeeper - Migrated Project CI from Jenkins to Github Actions on 2020-01-22. Releases - 4.10.0 was released on 2019-11-06. - 4.9.2 was released on 2019-05-16. - Supporting project Bookkeeper Visual Manager released v1.0.0 on 2020-04-12. ## Community Health: The community has been active in making infrastructural changes to Apache Bookkeeper this past quarter. We have had initiatives that moved us to Github Actions from Jenkins and also cut down the build and test time by more than 50%. Another development activity has seemed to go from mailing lists to our slack channel (apachebookkeeper.slack.com) where we had around 38 new users of Apache Bookkeeper. In the past quarter, the above activity has resulted in the following GitHub activity: - 38 PRs opened (8% increase) - 40 PRs closed (48% increase) - 50 commits (51% increase) - 20 code contributors (66% increase) Mailing List activity: - 1272 emails in issues@bookkeeper.apache.org (4% increase) - 30 emails in user@bookkeeper.apache.org - 59 emails in the dev@bookkeeper.apache.org - We'll be pushing to bring the discussions back to the mailing lists. Meetups and Conferences: - Several talks are scheduled for the Bookkeeper Track in the Apache Pulsar Summit 2020 to be held in 17 and 18th June 2020.

Pulsar Summit has a dedicated `bookkeeper` track for the community to present bookkeeper related talks. This will drive more participation from both communities. ### Committers We did not add any new committer within last year. We have a good amount of small contributions but no one is yet ready to be invited as committer. We are trying to engage more with current contributors. Most of current contributions come from other downstream Open Source projects that are using BookKeeper as building block. We got recent feedback of usage of BookKeeper and DistributeLog by new non open source projects. ### Activities dev@bookkeeper.apache.org had a 80% increase in traffic in the past quarter (123 emails compared to 68) user@bookkeeper.apache.org had a 271% increase in traffic in the past quarter (52 emails compared to 14) 32 commits in the past quarter (-40% decrease) 12 code contributors in the past quarter (-29% decrease) 32 PRs opened on GitHub, past quarter (-31% decrease) 25 PRs closed on GitHub, past quarter (-13% decrease) 25 issues opened on GitHub, past quarter (66% increase) 8 issues closed on GitHub, past quarter (100% increase)
## Description: BookKeeper is a scalable, fault-tolerant, and low-latency storage service optimized for append-only workloads. It has been used as a fundamental service to build high available and replicated services in companies like Twitter, Yahoo and Salesforce. It is also the log segment store for Apache DistributedLog and message store for Apache Pulsar. Apache DistributedLog is a high-level API and service layer for Apache BookKeeper, providing easier access to the BookKeeper primitives. It is a subproject of Apache BookKeeper. ## Issues: There are no issues requiring board attention at this time. ## Membership Data: Apache BookKeeper was founded 2014-11-19 (5 years ago) There are currently 21 committers and 16 PMC members in this project. The Committer-to-PMC ratio is roughly 3:2. Community changes, past quarter: - No new PMC members. Last addition was Charan Reddy G on 2019-07-24. - No new committers. Last addition was Andrey Yegorov on 2018-02-09. ## Project Activity: - 4.9.1 was released on April 7 2019 - 4.9.2 was released on May 16 2019 - 4.10.0: was released on November 6 2019 - The growth of Apache Pulsar community also help grow the adoption of BookKeeper. This helps building the ecosystem around BookKeeper. - The project is also extending its scope to cover long term distributed storage and now bundles a new KV distributed database (StreamStorage). - We released a new Python client for the StreamStorage service. - We are working on a brand new CLI interface GitHub issues: 19 issues opened on GitHub, past quarter (35% increase) 35 issues closed on GitHub, past quarter (191% increase) GitHub PR activity: 37 PRs opened on GitHub, past quarter (2% increase) 26 PRs closed on GitHub, past quarter (-33% decrease) ## Community Health: - During the last quarter there development slowed down a little and we missed one scheduled release (we started a Time based release plan this year). - During the last months new users and contributors appeared especially from Apache Pulsar community and from other OSS projects that were born recently and are based on Apache BookKeeper. - Mailing list discussions are brisk, in particularly around the active projects.

Last addition was Andrey Yegorov on 2018-02-10. ## Project Activity: Recent releases: 4.9.2 was released on 2019-05-17. 4.9.1 was released on 2019-04-06. 4.8.2 was released on 2019-03-18. 4.8.0 was released on 2018-09-25. Currently the community is working on releasing 4.10.0. The two releases will be going out soon. ## Community Health: The community is a bit slow. Because the committers and PMC members have a bit overlapped between Pulsar and BookKeeper. So a lot of them have been focused on growing the adoptions of Pulsar and hence BookKeeper. The adoptions of Pulsar has been increased a lot and so does BookKeeper. The members are able to put more focuses on BookKeeper in the next month.

Yahoo and Salesforce. It is also the log segment store for Apache DistributedLog and message store for Apache Pulsar.
## Issues:
There are no issues requiring board attention at this time.
## Activity:
- Apache DistributedLog graduates as a subproject of BookKeeper. We are consolidating the development efforts around
log stream library over bookkeeper.
- BookKeeper moves the development including issue reporting and tracking to Github. It reduces the barrier for people
to make contributions to bookkeeper.
- The 4.5.0 release which aims at merging 3 main branches is ready to release. The first release candidate is out on August 07.
- BookKeeper moves the website from CMS to Git. A new bookkeeper website along with tons of documentation improvements are made from contributors.
## Health report:
- After a year of development among develops from multiple different organizations, release 4.5 is almost complete. The first release candidate is out for vote on August 07. It includes exciting features like security support, netty 4 upgrade, weight-based placement policy.
- We moved the git repo to gitbox and are using Github for both issue management and pull request management. It reduced the gap for new contributors to engage with the community.
- DistributedLog graduates as a subproject.
- There are a few promising candidates based on the growth of the community and contributions from joining developers.

BookKeeper is a distributed, reliable, and high performance logging service. It has been used as a fundamental service to build high available and replicated services in companies like Twitter, Yahoo and Salesforce. It is also the log segment store for Apache DistributedLog (incubating). ## Issues: There are no issues requiring board attention at this time ## Activity: The mailing list activity has dropped and we attribute it to the split attention between Apache BookKeeper and the incubating project Apache DistributedLog. They are closely related given that DistributedLog uses BookKeeper as a building block for storing logs. Despite the drop of mailing list activity, there has been good discussion around upcoming features and improvements to the project. The community started organizing bi-weekly calls where everyone is invited to join. The goal is not to make decisions outside the mailing list and jira, but instead to have a better understanding of current proposals and problems that users of the project are facing. The community is also organizing a meetup that will happen in November. ## Health report: The community is making good progress. We have been having healthy discussions around issues and features and there are a few contributors on track to become. We haven't had a release in a while and we are targeting one for December 2016. ## PMC changes: - Currently 8 PMC members. - No new PMC members added in the last 3 months - Last PMC addition was Matteo Merli on Thu May 26 2016 ## Committer base changes: - Currently 11 committers. - No new committers added in the last 3 months - Last committer addition was JV Jujjuri at Thu Jun 09 2016 ## Releases: - Last release was 4.4.0 on Mon, 16 May 2016 ## Mailing list activity: The number of subscribers has been going up slightly. The drop in the traffic of the dev list we attribute to the split attention between the two related projects we mention above. - dev@bookkeeper.apache.org: - 77 subscribers (up 4 in the last 3 months): - 276 emails sent to list (512 in previous quarter) - issues@bookkeeper.apache.org: - 6 subscribers (up 0 in the last 3 months) - user@bookkeeper.apache.org: - 96 subscribers (up 4 in the last 3 months): - 12 emails sent to list (19 in previous quarter) ## JIRA activity: - 23 JIRA tickets created in the last 3 months - 6 JIRA tickets closed/resolved in the last 3 months
