ZooKeeper

15 Mar 2017 [Flavio Junqueira / Jim]

Report was filed, but display is awaiting the approval of the Board minutes.

21 Dec 2016 [Flavio Junqueira / Mark]

## Description:
Apache ZooKeeper is a system for distributed coordination. It enables
distributed systems to implement a variety of primitives and mechanisms that
are critical for such systems to function, e.g., distributed locks, master
election, group membership, and configuration.

## Issues:
There are no issues requiring board attention at this time.

## Activity:
The focus of the community has been to lift the alpha label of the 3.5 branch.
We have solved the main remaining issue (ZOOKEEPER-2014) and we are now getting
ready to release 3.5.3, which is supposed to be the last alpha release of the
3.5 branch.

The 3.5 branch has a number of important new features,
including reconfiguration, which has been the main culprit for the stabilization
of the branch.

We have additionally been preparing a new release of our stable branch, 3.4.10.
It will include bug fixes and one contribution that improves security for
server-to-server communication.

Both these releases are very close to coming out.

We have organized a meetup at the Facebook HQ back in November.

## Health report:
There has been a good amount of activity on all lists, new contributors, and new
features proposed. There are potentially new committers currently being discussed
on the private list.


## PMC changes:

 - Currently 11 PMC members.
 - No new PMC members added in the last 3 months
 - Last PMC addition was Chris Nauroth on Sun Aug 07 2016

## Committer base changes:

 - Currently 19 committers.
 - No new committers added in the last 3 months
 - Last committer addition was Chris Nauroth at Wed Sep 09 2015

## Releases:

 - Last release was 3.4.9 on Sat Sep 03 2016

## Mailing list activity:
 The activity on the dev list remained roughly constant while the activity of the
user list dropped. This is an artifact of questions now being asked on the dev list
mostly because they often involve more than just a clarification over the API. The
community has been favoring discussions on the dev list and slowly moving more
towards asking questions directly on that dev list. We don’t really make an effort
to have a clear separation between the two, although we suggest that API and use
case questions are better on the user list.


 - dev@zookeeper.apache.org:
    - 500 subscribers (up 2 in the last 3 months):
    - 3251 emails sent to list (3252 in previous quarter)

 - user@zookeeper.apache.org:
    - 1182 subscribers (up 6 in the last 3 months):
    - 186 emails sent to list (300 in previous quarter)


## JIRA activity:
The number of issues created has been greater than the number of issues resolved,
creating a backlog. We need more committer cycles to help with the backlog, and
we are working on inviting new committers.

 - 67 JIRA tickets created in the last 3 months
 - 33 JIRA tickets closed/resolved in the last 3 months

## Description:

 - Apache ZooKeeper is a system for distributed coordination. It enables
distributed systems to implement a variety of primitives and mechanisms that
are critical for such systems to function, e.g., distributed locks, master
election, group membership, and configuration.

## Issues:

 - There are no issues requiring board attention at this time.

## Activity:

 - For the last period, there are two points to highlight:
   * We have had two releases, one for the 3.4 branch and another for
     the 3.5. Releases of the 3.5 branch are still alpha, and the community
     has been working hard to resolve the issues pending to make it stable
     (GA).
   * Traffic on the dev list and number of commits has increases significantly
     compared to the last period. Traffic on the dev list has increased by
     roughly 70% while the traffic on the commit list has increased by over
     5x.  Interestingly, the number of subscribers to the dev list has dropped
     by 10 subscribers, which we attribute to natural churn.
## Health report:

 - The activity of the mailing list had dropped in the previous reporting
   periods, but it has picked up again from the current numbers. We did some
   effort to bring in new contributors by mentoring interested developers
   (e.g., developers who showed interest on the mailing list, developers we’ve
   met offline, meetups) and reached out to former contributors to help with
   closure on outstanding issues.
 - We have some potential committers coming, and we are considering offering
   committership to such contributors after the next upcoming release: 3.5.3.
   Their contributions have been strong so far.

## PMC changes:

 - Currently 11 PMC members.
 - Chris Nauroth was added to the PMC on Sun Aug 07 2016

## Committer base changes:

 - Currently 19 committers.
 - No new committers added in the last 3 months
 - Last committer addition was Chris Nauroth at Wed Sep 09 2015

## Releases:

 - 3.4.9 was released on Sat Sep 03 2016
 - 3.5.2 was released on Thu Jul 21 2016

## Mailing list activity:

 - dev@zookeeper.apache.org:
    - 499 subscribers (down -10 in the last 3 months):
    - 3285 emails sent to list (1917 in previous quarter)

 - user@zookeeper.apache.org:
    - 1178 subscribers (up 7 in the last 3 months):
    - 282 emails sent to list (267 in previous quarter)

 - The dev list traffic increased quite substantially from the previous period
   due to our efforts to increase the development activity. Interestingly, the
   number of subscribers dropped slightly, which we attribute to natural churn
   (e.g., people move on to a different project). The traffic of the user list
   has increased slightly, but not as much compared to the increase of the dev
   list. We have been getting the same rate of questions compared to the last
   period.

This release includes important features such as reconfiguration. It fixes
a significant number of bugs and includes smaller improvements both in
the server and client. The community is now focusing on the stability of the
branch. There is also ongoing work to introduce SSL support. This is a
feature that has been long awaited.

Apache BookKeeper (subproject)

Bookkeeper is a distributed, reliable, and high performance logging
service. The project also includes Hedwig which is a highly scalable
Pub/Sub service built on top of ZooKeeper and Bookkeeper with strong
durability guarantees.

We released version 4.2.3 on the 27th of June. The release was focussed
mainly on bugfixes and addressing operational annoyances.

We are currently voting on the first release candidate for version
4.3.0, so we expect that to be released within the next week. This
release includes a lot of improvements to the bookie on-disk
performance, a new statistics framework, and protobuffer protocol
support along with numerous bugfixes.

We welcomed one new committer, Rakesh Radhakrishnan, during the last
period. Once 4.3.0 is released, we also plan to extend committership to
a couple more people. We will all seek to become a TLP at that point.

ZooKeeper is a reliable coordination service for distributed systems.

Trunk is still under development for an eventual 3.5.0 release. A couple
of important improvements on the way for 3.5.0:

- One important new feature in 3.5.0 will be the ability to reconfigure
a ZooKeeper ensemble. This feature was discussed a long time in
ZOOKEEPER-107 and we have converged and committed it;
- We are also focusing on a number of improvements over the code that
performs recovery. In particular, we are targeting an implementation that
avoids sending and taking unnecessary snapshots, which reduces time to
recover in the presence of crashes.

Also, the release is supposed to address scalability, jdk7 and openjdk support,
maven build/rel, testing and audit logging. There are other various patches
we are working on related code cleanup and refactoring.

We have released 3.4.6 on March 10, 2014. 3.5.0 release date is not defined

ZooKeeper is a reliable coordination service for distributed applications.

Trunk is still under development for an eventual 3.5.0 release. A couple
of important improvements on the way for 3.5.0:

- One important new feature in 3.5.0 will be the ability to reconfigure
a ZooKeeper ensemble. This feature was discussed a long time in
ZOOKEEPER-107 and we have converged and committed it;
- We are also focusing on a number of improvements over the code that
performs recovery. In particular, we are targeting an implementation that
avoids sending and taking unnecessary snapshots, which reduces time to
recover in the presence of crashes.

Also, release is supposed to address scalability, jdk7 and openjdk support,
maven build/rel, testing and audit logging. There are other various patches
we are working on related code cleanup and refactoring.

Note that the status of releases hasn't changed since the last board report.
3.5.0 release date is not defined yet.

A bug fix release 3.4.6 is also expected to go out soon. There are two jiras
currently blocking the release.

The last release has been 3.4.5 on November 18, 2012.

No infrastructure issues.

=== BookKeeper (subproject)

Bookkeeper is a distributed, reliable, and high performance logging service.
The project also includes Hedwig which is a highly scalable Pub/Sub service
built on top of ZooKeeper and Bookkeeper with strong durability guarantees.

We released Bookkeeper 4.2.2 on the 10th October 2013. This was a bugfix
release, but also exposed some new administrative functions for dealing with
ledgers.

We continue to work towards 4.3.0. The final scope of the release has been
decided on. It will include improved bookie on-disk performance, a new
statistics collection framework and SSL support, among other things. We
hope to release 4.3.0 in Q1 of 2014.

Focus in the last quarter has been on the 4.2.2 release which at the
time of writing has a release candidate under consideration. 4.2.2 is
a mostly a bugfix release, though we have also exposed some new
administrative functionality.

Release 4.3.0 is still being worked on, though scope may be reduced to
allow for a more regular release cycle.

Infrastructure issues:

Graduation:
The community overall feels that we should consider graduation after
release 4.3.0. We plan to have release 4.3.0 before the end of this

Recently the new S4 project has been accepted into the Incubator -- it
is using ZooKeeper.

A discussion is currently under way regarding the possibility of
merging the recently open sourced "Curator" source base from
Netflix. These are client implementations of ZooKeeper "recipes"
(e.g. leadership election, group membership, etc...) which simplify
the act of using ZooKeeper in client side applications.

The authors of Curator are unwilling to join the incubator, this is
based on their past experience as well as some of the ongoing issues
they are seeing wrt projects entering the incubator. They have
expressed a preference to come in either as a subproject or as a
separate release artifact of the TLP.

A public meetup has been discussed for January and is currently being
debated/planned on the ZooKeeper developer's list.

months, an umbrella JIRA is available for tracking progress:
https://issues.apache.org/jira/browse/ZOOKEEPER-940

Over the last month porting of the legacy site to the new TLP location
http://zookeeper.apache.org/ has completed. All wiki pages have also
been moved to cwiki
https://cwiki.apache.org/confluence/display/ZOOKEEPER/Index

All requirements detailed on the project branding requirements page
have been integrated into the new TLP website:
http://www.apache.org/foundation/marks/pmcs.html

Bylaws have been voted on and approved
http://zookeeper.apache.org/bylaws.html

Release management guidelines have been put in place:
https://cwiki.apache.org/confluence/display/ZOOKEEPER/ReleaseManagement

Guidelines for committership are being worked out:
https://cwiki.apache.org/confluence/display/ZOOKEEPER/CommitterCriteria

New committers:
None. However this issue has been under active discussion for the past
several months. Now that TLP related work is completed we are
officially considering a number of new committers (contributors we've
been actively mentoring).

Two releases are in progress, near term (Q1) a 3.3.3 fix release
(RM assigned), and longer term 3.4.0 feature release.

The ZooKeeper PMC has voted to accept "Clusterlib" as a subproject
(probably under a different, less general name):
