The decrease can be attributed to the 1.15.0 release process, which dominated the mailing list traffic last quarter. Additionally, a long-standing trend has been that communication between developers and users tends to happen over both public and private IMs. - Public IM activity over the community Slack channel is up slightly, measured by daily active users (+14%) and weekly active users (+13%). - Development activity measured in the number of commits has decreased (-52%) from 15 unique contributors (+25%), three of whom are new to the project. The drop can be attributed to some senior contributors shifting focus (either away from code contribution to the project, or away from the project entirely). - Development activity measured by opened and closed issues has decreased (-30% opened tickets, -61% closed tickets), again partially due to the shift in focus of some contributors, and also due to the large granularity of certain features being worked on. - Website traffic decreased slightly, with -3.6% measured number of users and -7.5% sessions in the last 90 days, according to Google Analytics.

Last addition was Bankim Bhavsar on 2020-04-17. ## Project Activity: Recent releases: - 1.13.0 was released on 2020-09-17. - 1.12.0 was released on 2020-05-11. - 1.10.1 was released on 2019-11-20. - 1.11.1 was released on 2019-11-20. ## Community Health: - Traffic to the dev mailing list increased slightly (3%) in the last quarter, though traffic to the users mailing list has dropped significantly (-49%). - Website traffic decreased slightly, with between 0% and 6% decreases measured in users, new users, sessions, page views, and page sessions, according to Google Analytics. - Public IM activity over the community Slack channel is down somewhat, with the average daily number of posts in public channels having dropped 23%, and weekly and daily active users averaged across the quarters dipping 14% and 19% respectively. - Development activity measured in the number of commits has dropped slightly (-2%) by 13 unique contributors (-35%), 6 of which were first-time contributors to Kudu. Development activity measured by opened and closed issues has decreased (-49% opened tickets, -84% closed tickets), likely due to the fact that a few larger features are currently being worked with sub-tasks that are not tracked on Jira.

The memkind library was added as a dependency to this version. This depends on libnuma which is licensed under LGPL. We released 1.11.0 before noticing the issue and then released both 1.10.1 and 1.11.1 to address the issue. Details on this can be found in the release notes and in KUDU-2990. Recent releases: - 1.10.1 was released on 2019-11-20. - 1.11.1 was released on 2019-11-20. - 1.10.0 was released on 2019-11-01. ## Community Health: - Traffic to the dev mailing list is up by 190% which can be attributed to the 3 releases and several other larger topics we discussed on the list. User list traffic is down 30%. - Website traffic is slightly down, by 7% both by number of unique users and visits. - Developer activity is up by every metric we track, except for open JIRAs (down 15%): reviews +40%, issues closed +16%, commits +80%. - Code was authored by 23 contributors (down 4% since last quarter), 6 of which are new to the project.

## Project Activity:
The community is in the process of preparing the next minor version release,
Apache Kudu 1.11.0.
The previous release was Apache Kudu 1.10.0, on Tue Jul 9 2019.
## Community Health:
- Traffic to the dev mailing list is down by 47%. Most threads are responded
to in a timely manner, but this decline can be explained by developers'
preference to instant messaging and face-to-face conversations that get
eventually distilled and shared with the mailing list.
- Website traffic appears largely flat, with the number of users down 4%,
sessions down 3%, and average session duration up 4%.
- Developer activity (measured by code reviews, commits, open JIRAs, and
closed JIRA) is noticeably down (35%, 55%, 41%, 68% respectively). The
previous quarter saw many large, multi-quarter feature efforts come to a
close, and so this decline is understandable, with a few larger projects
beginning their design phases.
- Commits were authored by 24 contributors (-14% since last quarter), 5 of
which are new to the project.
## Report Feedback
In response to our last report, the board offered this feedback:
druggeri: I can appreciate the comment about using instant messaging
rather than mailing list. Just to be clear, is the project
being sure to return all decisions back to the mailing
list?
We have been congnizant of this and have tried to ensure that once discussed,
important topics are surfaced to the mailing lists with in-depth summaries of
the discussion so far, allowing for further discussion.
WHEREAS, the Board of Directors heretofore appointed Todd Lipcon (todd) to the office of Vice President, Apache Kudu, and WHEREAS, the Board of Directors is in receipt of the resignation of Todd Lipcon from the office of Vice President, Apache Kudu, and WHEREAS, the Project Management Committee of the Apache Kudu project has chosen by vote to recommend Adar Dembo (adar) as the successor to the post; NOW, THEREFORE, BE IT RESOLVED, that Todd Lipcon is relieved and discharged from the duties and responsibilities of the office of Vice President, Apache Kudu, and BE IT FURTHER RESOLVED, that Adar Dembo be and hereby is appointed to the office of Vice President, Apache Kudu, 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.

## Description: - Apache Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. ## Issues: - There are no issues requiring board attention at this time. ## Activity: - Apache Kudu 1.10.0 has been released with several long-awaited new features and improvements, including fine-grained authorization backed by Apache Sentry, synchronization of metadata with Apache Hive Metastore, and table backup and restore using Apache Spark. ## Health report: - User and dev mailing list subscriber growth up by 3% and 4% respectively, but their traffic is down by 36% and 21% respectively. Most questions are answered relatively quickly, but this decline can most likely be explained by people preferring instant messaging on Slack over the mailing list. - Website traffic remains the same, users and sessions both up less than 1%. We continued working on the revival of the blog with 2 new posts, although both were published early in the quarter. The blog traffic is up significantly, page views and unique page views both up by 20% compared to last quarter's traffic. - Development activity (measured by code review, JIRA traffic and number of commits) is up overall (reviews -2%, issues +37%, commits +10%). Commits were authored by 22 unique contributors (-1 since last quarter). ## PMC changes: - Currently 22 PMC members. - Yingchun Lai was added to the PMC on Wed Jun 05 2019 ## Committer base changes: - Currently 22 committers. - Yingchun Lai was added as a committer on Thu May 30 2019 ## Releases: - Last release was 1.10.0 on Tue Jul 9 2019 ## JIRA activity: - 120 JIRA tickets created in the last 3 months - 101 JIRA tickets closed/resolved in the last 3 months
## Description:
- Apache Kudu is a distributed columnar storage engine built for the Apache
Hadoop ecosystem.
## Issues:
- There are no issues requiring board attention at this time
## Activity:
- Apache Kudu 1.9.0 was released on Mar 11 2019, which includes several new
features like location awareness, experimental Docker support for testing
and development, and support for writing Java tests against Kudu without
having to build it locally by making platform-specific binaries available
through Gradle and Maven.
## Health report:
- User and dev mailing list subscriber growth are both insignificant (less
than 2%), but the traffic on the user list decreased by 8% while the dev
list's traffic increased by 90%.
- Website traffic remains the same, users and sessions both up 1%. In the
previous reports we talked about reviving the blog, in this quarter we
published 2 new posts excluding the release announcement. The section's
traffic is up, by 4% and 15% for users and sessions respectively.
- Development activity (measured by code review, JIRA traffic and number of
commits) is up (reviews +58%, issues +62%, commits +1%). Code was authored
by 23 unique contributors (+7 since last quarter).

## Mailing list activity:
- The traffic on the dev@ list is significant, there was a lot of discussion
about the 1.9.0 release, the migration to GitBox and whether to use GitHub
for contributions and code reviews aside from the regular discussions.

## Description: - Apache Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. ## Issues: - No issues requiring the board's attention at this time. ## Activity: - Kudu 1.8.0 was released on October 23rd, 2018, with support for a manual rebalancer that can be used to redistribute table replicas among tablet servers. The release also included the usual bevy of bug fixes and performance improvements, as well as some smaller features based on user and operator feedback from past releases. ## Health report: - User mailing list subscriptions didn't grow, and traffic is down about 25% this quarter, most likely due to US holidays. Questions are generally answered quickly and overall traffic is quite bursty. - Website traffic growth is down: about -7% for users and -9% for sessions since the last quarter. This is within our normal quarterly fluctuation. In the last board report we talked about reviving the Kudu blog to grow interest in the project, and although that hasn't happened yet, we do have several blog posts currently in review. - Development activity (measured by code review and JIRA traffic) is down somewhat (reviews -9%, JIRA -20%, commits +36%). Code was authored by 16 unique contributors (-12 since last quarter) of whom 2 were new to the project (-7 since last quarter). Commit activity was inflated due to the 1.8.0 release; the rest of the metrics reflect the fact that several key developers have tapered down their involvement in Kudu for various reasons. - In the last board report we wrote about how we're working on a process to publish test artifacts as part of Kudu releases. Progress has been made but the new process is not yet ready for primetime. ## PMC changes: - Currently 21 PMC members. - No new PMC members in the last 3 months. - Last PMC addition: Sun Jul 22 2018 (Attila Bukor) ## Committer base changes: - Currently 21 committers. - No new committers in the last 3 months. - Last committer addition: Mon Jul 23 2018 (Attila Bukor) ## Releases: - Last release was 1.8.0 on Tue Oct 23 2018 ## JIRA activity: - 54 JIRA tickets created in the last 3 months - 49 JIRA tickets closed/resolved in the last 3 months
## Description:
- Apache Kudu is a distributed columnar storage engine built for the Apache
Hadoop ecosystem.
## Issues:
- No issues requiring the board's attention at this time.
## Activity:
- Since the last report, we haven't had any releases (the last release was
1.7.1, on June 7th). However, we are working on the next minor release which
we expect to publish in mid-October. It will include the usual bevy of bug
fixes and performance improvements, as well as some smaller features based on
user and operator feedback from past releases.
## Health report:
- User mailing list subscriptions didn't grow, and traffic was up 10% this
quarter. We've noted this in past board reports but it bears repeating: it's
difficult to learn anything from these metrics. Questions are generally
answered quickly and overall traffic is quite bursty.
- Website traffic growth is down slightly: about -2% for users and -5% for
sessions since the last quarter. This is within our normal quarterly
fluctuation. Relatedly, the Kudu blog has been quiet for most of 2018, but
we've been working to change that. We published two new posts in September
which is a lot when the average monthly post count is zero.
- Development activity (measured by code review and JIRA traffic) is down
slightly (reviews -13%, JIRA +12%, commits -17%). Code was authored by
28 unique contributors (+10 since last quarter) of whom 9 were new to the
project (+6 since last quarter). So no real change in activity, though
it's heartening to see so many different contributors, and quite a few of
them new to the project at that.
- We've been working on a process to publish test artifacts as part of Kudu
releases so that other projects can better test their Kudu integrations. An
Apache Beam contributor helped develop a proof of concept which can be found
here: https://s.apache.org/dj5N.

## Description: Apache Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. ## Issues: No issues requiring the board's attention at this time. ## Activity: Since the last report, we've made one maintenance release (1.7.1). The 1.7.1 release included critical bug fixes discovered in 1.7.0. Work continues on further new features including deeper integration with Apache Hive, support for backup and recovery (using Apache Spark as an execution building block), and more. ## Health report: - User mailing list didn't grow much in this quarter, and traffic was also down 10%. It's hard to discern an obvious pattern here - most questions are answered relatively quickly after they appear on the list. Perhaps we are doing a good job of improving documentation and, as common questions are captured in the mailing list archives, fewer people need to ask questions on the list? - Website traffic growth is up a bit: Around +6% for both users and sessions vs the prior quarter. The previous report asked how these numbers are calculated. We are currently using Google Analytics on our site. - Development activity (measured by code review and JIRA traffic) is down noticeably (reviews -14%, JIRA -40%, commits -36%). Code was authored by 18 unique contributors (-4 since last quarter) of whom 3 were new to the project (-5 since last quarter). Again no obvious trend here since activity was way up last quarter -- just seems to be a noisy metric. - It's been a while since we added a committer, but some promising votes are currently going on on the private list. ## PMC changes: - Currently 19 PMC members. - No new PMC members added in the last 3 months - Last PMC addition was Hao Hao on Wed Dec 13 2017 ## Committer base changes: - Currently 19 committers. - No new committers added in the last 3 months - Last committer addition was Hao Hao at Wed Dec 13 2017 ## Releases: - 1.7.1 was released on Wed Jun 06 2018 ## JIRA activity: - 91 JIRA tickets created in the last 3 months - 64 JIRA tickets closed/resolved in the last 3 months
## Description: Apache Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. ## Issues: No issues requiring the board's attention at this time. ## Activity: Since the last report, we've made one minor release (1.7.0). The 1.7.0 release included some major improvements to our design for re-replicating data after machine failure, support for DECIMAL types, and various other smaller features and improvements based on user and operator feedback from prior releases. ## Health report: - User mailing list growth continues at historical rates (8% this quarter). User list traffic is down again after a bump up in the previous quarter. Looking historically it seems like "messages sent" is a pretty noisy metric with big bursts of activity due to popular threads, followed by periods of quietness. We don't believe there is anything to be learned from this. - Website traffic grew again slightly - sessions +2.7%, users +2.3%. - Development activity grew substantially (measured by code review and JIRA traffic): reviews +34%, jira +119%. In the previous report we mentioned that it was down due to the holiday season so this is likely just the normal activity resuming in the new year. - This quarter (Jan-Mar), we committed code authored by 22 distinct contributors (+5 since last quarter) of whom 8 (+5 since last quarter) were new to the project. ## PMC changes: - Currently 19 PMC members. - No new PMC members added in the last 3 months - Last PMC addition was Hao Hao on Wed Dec 13 2017 ## Committer base changes: - Currently 19 committers. - No new committers added in the last 3 months - Last committer addition was Hao Hao at Wed Dec 13 2017 ## Releases: - 1.7.0 was released on Tue Mar 20 2018 ## JIRA activity: - 150 JIRA tickets created in the last 3 months - 96 JIRA tickets closed/resolved in the last 3 months
## Description:
Apache Kudu is a distributed columnar storage engine built for the Apache
Hadoop ecosystem.
## Issues:
No issues requiring the board's attention at this time.
## Activity:
Since the last report, we've made one minor release (1.6.0).
The 1.6.0 release focused on bug fixes, stability, and performance. Notably,
Kudu can now gracefully handle failures of local disk drives without crashing
the process.
Work over the holiday period has been a bit slower, but we continue
to make progress around similar goals of stability and easier operations
for our next release.
In response to our last report, the board offered this feedback:
rb: Some projects find that separating committer and PMC gives you
the opportunity to be more generous with commit rights without
necessarily adding everyone to the PMC. It would be a shame to
have those 6 new contributors go away feeling unwelcomed.
We discussed this briefly on the private list and the consensus seemed to be
that we haven't felt any hesitation to add committers due to the combined
PMC/committer list. In this period we added three new PMC/committers so we
don't feel like splitting the list is necessary at this point.
## Health report:
- Subscriptions to the user mailing list are up slightly over last quarter.
In the previous quarter we noted that mailing list traffic was significantly
down, but in this quarter it has doubled back to previous levels.
It appears that the quiet couple of months was not indicative of any
trend.
- Website traffic is slightly up (unique users up 4.4%, sessions up 8.6%).
This is within our normal quarterly fluctuation.
- Development activity as measured by code reviews and JIRA traffic is down
a bit from the previous quarter, probably due to the holiday season.
- This quarter (Oct-Dec), we committed code authored by 17 distinct
contributors, of whom 3 were new to the project. We added three new
committers and PMC members.
- Collaboration continues with the Apache Impala project around our shared
RPC library code. This has been beneficial to both projects.
## PMC/Committer changes:
- Currently 19 PMC members and committers (all committers are PMC)
- Last committer/PMC additions:
-- Andrew Wong was added as a committer and PMC on Mon Oct 30 2017
-- Grant Henke was added as a committer and PMC on Fri Oct 27 2017
-- Hao Hao was added as a committer and PMC on Wed Dec 13 2017
## Releases:
- Apache Kudu 1.6.0 was released on December 6th, 2017.
## Description: Apache Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. ## Issues: No issues requiring the board's attention at this time. ## Activity: Since the last report, we've made one minor release (1.5.0). Development continues in the same areas as the last report: operability, stability, security, and incremental performance improvements. We plan to continue making minor releases with no reason for a major (compatibility-breaking) release on the horizon. ## Health report: - Subscriptions to the user mailing list are up slightly over last quarter, but traffic down significantly. It's not clear if there is anything to learn from this, but we'll make sure to look over recent weeks and see if any questions have been going un-answered. - Website traffic (unique user count) is down about 9% since last quarter. Our blog continues to be rather quiet of late -- contributors have spent more time on code and less on publicity. A few posts are now in the queue and hoping they'll bring this back up next quarter. - Development velocity is pretty constant from last quarter measured by review traffic and JIRA (commits slightly down, JIRA up significantly, reviews about even). - This quarter (July-Sep), we committed code authored by 24 distinct contributors, of whom 6 were new to the project. Similar diversity and growth. Discussion continues on the private list for new committers. The latest discussions were positive and seems like a vote should be called soon. - The Kudu project has been collaborating closely with the Impala incubator podling community. Specifically, Impala is adopting Kudu's RPC library for their own internal usage. This is in addition to the actual user-facing integration between the projects that has been ongoing for upwards of a year. This has resulted in a number of new Kudu contributions from committers on that project. ## PMC/Committer changes: - Currently 16 PMC members and committers (all committers are PMC) - Last committer/PMC addition: Jordan Birdsell was added on Nov 8, 2016. ## Releases: - Apache Kudu 1.5.0 was released on September 13, 2017.
## Description: Apache Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. ## Issues: No issues requiring the board's attention at this time. ## Activity: Since the last report, we've made one minor release (1.4.0) and one patch release (1.3.1). Development continues to focus around operability, stability, security, and incremental performance improvements. We plan to continue making minor releases with no reason for a major (compatibility-breaking) release on the horizon. ## Health report: - Subscriptions to the user mailing list are up 9% over last quarter, with traffic up 20%. Subscriptions to development-related lists have grown at a similar rate (~9%), with traffic about even. Questions on both the mailing list and our Slack channel are typically answered within a day. - Website traffic (unique user count) is down about 20% since last quarter. We attribute this to two factors: (1) less regular postings on our blog, and (2) a big spike of traffic due to some vendor announcements falling in Q1. - Development velocity is pretty constant from last quarter (within 10% on reviews and commits, JIRA a bit down due to natural fluctuations) - This quarter (April-Jun), we committed code authored by 21 distinct contributors, of whom 8 were new to the project. Of the 8 new contributors, 5 are unaffiliated with Cloudera, who employs the majority of active committers. This follows the pattern over the previous several quarters. We are continuing to keep an eye out for committer candidates -- some of the newer contributors are getting close to the thresholds at which we have previously invited new contributors. The PMC expects to discuss and likely add new committers this coming quarter. ## PMC/Committer changes: - Currently 16 PMC members and committers (all committers are PMC) - Last committer/PMC addition: Jordan Birdsell was added on Nov 8, 2016. ## Releases: - Apache Kudu 1.4.0 was released on June 13, 2017. - Apache Kudu 1.3.1 was released on April 19, 2017.
## Description: Apache Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. ## Issues: No issues requiring the board's attention at this time. ## Activity: Since the last report, we've made two minor releases: 1.2 just after the prior report, and 1.3 a few weeks back. Kudu 1.3 is an important milestone for the project, as it now includes support for strong authentication (via Kerberos) and TLS wire encryption. Based on feedback from the community over the last year, we think this will substantially increase adoption in environments with more requirements around data security. ## Health report: - Subscriptions to the user mailing list are up 8% over last quarter, with traffic up 14%. Subscriptions to development-related lists have grown at a similar rate (~9%), with traffic down 30%. The drop in dev traffic just seems to be natural fluctuation of design discussion vs implementation focus of the team. Questions on both the mailing list and our Slack channel are typically answered within a day. - Global interest in Apache Kudu continues to increase at a good clip. Website traffic (by user count) on http://kudu.apache.org/ was up 73% this quarter vs last. - Development velocity is pretty constant from last quarter (commits and JIRA traffic about constant, code review traffic +10%). - This quarter (Jan-Mar), we committed code authored by 26 distinct contributors, of whom 8 were new to the project. Of the 8 new contributors, 5 are unaffiliated with Cloudera, who employs the majority of active committers. We reported similar stats last quarter, and noted that we are happy with the diversity of contributors. The board noted "hopefully some of these new contributors will develop into committers". We are keeping an eye out for potential committers, but we have mostly observed a "long tail" pattern -- of the 37 non-committer contributors over the past year, 23 have contributed only one or two patches, so we don't feel that any is yet ready for committership. We'll continue to keep an eye out for potential committers over the coming quarter. If the above pattern persists, we will consider surveying the "long tail" contributors to see if there are any changes we could make to encourage continued participation. ## PMC/Committer changes: - Currently 16 PMC members and committers (all committers are PMC) - Last committer/PMC addition: Jordan Birdsell was added on Nov 8, 2016. ## Releases: - Apache Kudu 1.3.0 was released on March 20, 2017. - Apache Kudu 1.2.0 was released on January 18, 2017.
## Description: Apache Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. ## Issues: No issues requiring the board's attention at this time. ## Activity: Since the last report, we've made one minor release and one bug fix release. Additionally, we branched for Kudu 1.2 which we expect to release by the end of January. In addition to the features that have landed in Kudu 1.1 and the upcoming 1.2, we have also made initial progress on adding various security-related functionality to Kudu. It is not yet usable by end users, but some infrastructure has landed in our master branch and we expect to provide some basic security functionality in Kudu 1.3. Many users have cited lack of security functionality as a barrier to adoption, so we expect to see an up-tick in usage later this year as it becomes available. ## Health report: - Subscriptions to the user mailing list are up 14% over last quarter, with a comparable growth in traffic. Subscriptions to development-related lists have grown at a slower rate (~5%). Questions on both the mailing list and our Slack channel are typically answered within a day. - Development velocity (as measured by commits and dev list traffic) is is slightly down from the previous quarter, likely due to a relatively quiet holiday period in December. That said, absolute levels are still healthy (4-5 commits per day) - This quarter, we committed code authored by 21 distinct contributors, of whom 9 were new to the project. Of the 9 new contributors, 7 are unaffiliated with Cloudera, who employs the majority of active committers. This is a good sign for long term project diversity, though we still need to cultivate the new contributors and encourage continued involvement. ## PMC/Committer changes: - Currently 16 PMC members and committers (all committers are PMC) - Last committer/PMC addition: Jordan Birdsell was added on Nov 8, 2016. ## Releases: - Apache Kudu 1.0.1 was released on Tue Oct 11 2016 - Apache Kudu 1.1.0 was released on Mon Nov 21 2016
Apache Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. ## Issues: No issues requiring the board's attention at this time. ## Activity: Since the last report: - We released Kudu 1.0 in mid September, and issued a corresponding press release. Thanks, Sally, for the support! - The 1.0 release and corresponding press generated record traffic to our project web site. It has since tapered off but remains higher than historic levels. - The community is currently voting on a 1.0.1 bug-fix release to address a few issues discovered in 1.0.0. - Kudu was featured in 5 talks at the Strata+Hadoop World conference in NYC in September. Two talks were delivered by a member of the PMC, but three were delivered by real-world users about their use cases. These user talks had positive things to say about their adoption. ## Health report: - Mailing list subscribership is up slightly in the last month, and traffic is stable. - We committed code from one brand new contributor in the past month. Many new users have shown up on mailing lists and our Slack-based user chat. - JIRA tickets are being created at a slightly higher rate than they are being resolved, as a lot of contributors are working on scoping out upcoming post-1.0 development work. Nevertheless, new bugs reported by users are being triaged and addressed quickly. ## PMC/Committer changes: - Currently 15 PMC members and committers (all committers are PMC) - Last committer/PMC additions: 2 added on 9/14/2016. ## Releases: - September 19, 2016: Kudu 1.0.0 released.

Kudu is a distributed columnar storage engine built for the Apache Hadoop
ecosystem.
Kudu has been incubating since 2015-12-03.
Three most important issues to address in the move towards graduation:
1. Build a more diverse developer and user community
2. Migrate our web site under apache.org
3. Continue to make regular Apache releases
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
of?
None.
How has the community developed since the last report?
The PPMC invited Binglin Chang as a new committer and PPMC member. Binglin
has continued to increase his involvement and some of his colleagues are
now becoming more involved as well.
Since the last report, we had contributions from several new contributors,
including five new contributors from outside Cloudera (the initial code
grantor). Of those, two were substantial pieces of new functionality: a
new sink to ingest data from Apache Flume, and an improved integration
with Apache Spark. We hope that the authors of these contributions will
continue to be involved in the community and grow into committers.
In March, one of our mentors approached the development community with
some ideas to make the project more approachable for developers. As a
result of this, we've been working on a few action items:
1) We started a project blog and have been posting weekly updates on
development progress as well as more detailed posts on new features or
project news. We've heard from community members that this is an easy
way to track the project without subscribing to high-volume dev lists.
2) Our dev@ list is currently very noisy with a lot of code review
comments. For more casual contributors this can be overwhelming as
code review is intermingled with higher level project discussions. The
community discussed the issue and decided to split the code review
traffic to a new mailing list (currently awaiting infra to create it)
3) We've started an informal policy of emailing the dev list with a
heads-up whenever any new larger feature first shows up on gerrit or
JIRA, to make it easier for people to give input on large items without
having to see every bug fix or small improvement. For example, whenever
design discussion starts on a new feature, the contributor sends a
'heads-up' email to dev@.
Development activity continues to be healthy. Mailing list traffic for the
dev list in April and May was similar to the preceding months. Patch
contribution level is also fairly stable (50-80 commits/month) with lulls
around releases as people focus on release testing, documentation, etc.
User mailing list traffic is steadily increasing in quantity and
diversity: 108 messages in April vs 51 in March, 40 in Feb. April saw 26
distinct people contribute to the user list discussion vs 15 in Feb.
Website traffic also indicates growing interest, with April having 30%
more traffic than Feb.
In the last two months, Kudu-related talks were delivered in San
Francisco, San Jose, Beijing, Boston, DC, Detroit, London, and Dublin.
More talks are scheduled for the upcoming months at ApacheCon Big Data,
Strata/Hadoop World, Berlin Buzzwords, and various local meetups.
How has the project developed since the last report?
Since the last report, we've accomplished the following milestones:
- We released Apache Kudu 0.7.1-incubating on 3/9/2016 to fix a few issues
found in the 0.7.0 release.
- We released Apache Kudu 0.8.0-incubating on 4/10/2016 with various new
features and improvements.
Date of last release:
April 10, 2016: Apache Kudu 0.8.0-incubating
When were the last committers or PMC members elected?
- Binglin Chang was added as a committer and PPMC member on April 4, 2016.

Continue to make regular Apache releases Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? None. How has the community developed since the last report? - In February, we only received one patch from a new contributor (3 total from non-committers). We're continuing to focus on building a more diverse developer community. Although recruiting new contributors to Kudu itself have been slow, we had community members report beginnings of a Presto integration, an Apache Flume sink, and Rust language bindings. We are considering whether it makes sense to develop these things within the Kudu project or external locations. - Overall development velocity continues to be pretty good: 94 patches committed since the last report, representing about 3.5kloc of new code and 4kloc of changes. This is slightly down from last month, as we spent a bit more time on managing our first release and fixing bugs rather than adding new features. Dev list traffic is similar to January (1032 messages vs 1144 in Jan). - Community members continue to give public talks about Kudu at various conferences and meetups. Talks were delivered at conferences or meetups in Tokyo (x2), Sunnyvale, Krakow, San Francisco (x2), and Seattle. More are planned for March. We are also encouraged that at least two Kudu meetup talks were delivered by new members of the community outside the core development team. We hope to see the "grassroots community" trend continue. - The public Kudu Slack channel continues to be popular. It has grown from 116 members last month to 150 this month. Discussion between users and devs is quite active, with daily participation from a global community (USA, China, Poland, Japan, et al). Many users seem to prefer this method over the traditional user mailing list. How has the project developed since the last report? Since the last report, we've accomplished the following milestones: - We successfully migrated our issue tracking to the Apache JIRA. Special thanks to Gavin on the infra team and Mike Percy on the Kudu project for hard work on this transition. - We cleaned up our license documentation and successfully published our first official release as an incubating project (0.7.0)! Date of last release: Feb 25, 2016: Apache Kudu 0.7.0-incubating When were the last committers or PMC members elected? None since initial incubation.

Kudu is a distributed columnar storage engine built for the Apache Hadoop ecosystem. Kudu has been incubating since 2015-12-03. Three most important issues to address in the move towards graduation: 1. Continue to move over infrastructure (JIRA, etc) to ASF 2. Build a more diverse development and user community 3. Perform releases under the ASF Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? None. How has the community developed since the last report? - In January, we have received patches from three new contributors. The patches were of varying size (from trivial to quite significant) but we're encouraged that new developers are finding the patch submission process approachable. - Overall >110 patches were committed in January from 11 developers representing three organizations. Discounting some large patches which replaced our copyright boilerplate, license notices, etc, around 10-12kloc were changed in January. This is a substantial increase compared to December which had only 29 patches, representing less than 1000 lines of changed code. Lines of code are not a primary metric we track, but the above shows that the community is getting back into rapid and lively development after a lull during the holiday season. This is also evident in the dev list traffic (1084 messages so far in January). - Community members continue to give public talks about Kudu at various conferences and meetups. Talks were delivered at meetups in Atlanta and Palo Alto, and more are being scheduled for the coming months. - The public Kudu Slack channel has proven fairly popular among both the developer and user communities. The group now has 116 members, of which ~20 are typically active on an average weekday. How has the project developed since the last report? Since the last report, we've accomplished the following milestones: - We set up a workflow and scripting for committers to easily push work that has been reviewed on Gerrit into our official ASF repository. We are following the best practices established by the AsterixDB podling. - We moved over our user and developer discussions to ASF mailing lists and discontinued usage of our old Google Groups. Migration of JIRA is an ongoing project which we hope to close out this coming month. - We set up publicly-accessible precommit builds so that non-Cloudera contributors can see automated test results for their contributions. - We adjusted our licensing boilerplate and documentation to comply with our understanding of ASF policies. We also started to build scripting for doing ASF-style source releases. We are planning on doing our first release in the incubator in early Feb. Date of last release: None under the ASF. Outside of the ASF, we released 0.6.0 on 11/24/2015. When were the last committers or PMC members elected? None since initial incubation.

3. Perform releases under the ASF
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
None so far.
How has the community developed since the last report?
- The development community has remained about the same since the initial
proposal, with overall code contribution levels a bit lower than
historical averages due to the end-of-year holidays.
- Xiaomi reported that they are now running Kudu in a production use case
on ~70 nodes ingesting 10B rows/day. This is Kudu's first known
production use case, and we expect continuing and increasing
participation from developers at Xiaomi.
- To spread the word about Kudu, various community members have given a
number of talks over the last 6 weeks, including: Strata/Hadoop World
(Singapore), Big Data Tech Con (Beijing), Shanghai Streaming Meetup,
Korea Big Data Think Tank (Seoul), San Francisco Spark Hackers, The Hive
Big Data Think Tank (Palo Alto), Charlotte Hadoop User Group, Cloudera
World Tokyo, Big Data Warehousing Meetup (NYC), and more.
- Members of the Kudu community met up with Apache Drill contributors and
built an initial version of Kudu/Drill integration. We anticipate
further collaboration with Drill and other ASF TLPs.
How has the project developed since the last report?
This is our first report since incubation. In the past month, we've
accomplished a few milestones:
- filed an SGA as well as ICLAs for initial committers
- granted karma, created mailing lists, and subscribed mentors/committers
- updated our web site to comply with ASF branding
- filed INFRA requests to start working on git and JIRA migration
(INFRA-10959, INFRA-10983)
Progress has slowed in the second half of December due to the holiday
season, but we anticipate picking momentum back up in January.
Date of last release:
None under the ASF. Outside of the ASF, we released 0.6.0 on 11/24/2015.
When were the last committers or PMC members elected?
None since initial incubation.
