Incubator PMC report for September 2019

The Apache Incubator is the entry path into the ASF for projects and codebases wishing to become part of the Foundation's efforts.

This monthly report is in markdown so that it's easier to read. If you are not viewing this in that format, it can be seen here: https://cwiki.apache.org/confluence/display/INCUBATOR/September2019

There are presently 48 podlings incubating. In August, podlings executed TODO distinct releases. We added three new IPMC members and no IPMC members retired.

We have one new podling this month DolphinScheduler. There have been a couple of ongoing enquires about new projects, and some proposals are being worked on. A couple of podlings are heading towards graduation in the next few months. Druid was up for graduation last month but withdrew as there's a trademark issue with its name.

Several podlings Amaterasu, Marvin-AI, Superset, Tamaya and Tephra didn't submit a report and have been asked to do so next month. This includes podling Tamaya which have now failed to report twice in a row.

Amaterasu has failed to reports three times in a row. It looks like the PPMC is missing and there's little or no activity on the list. One final chance will be given to the project to explain what it status it and how it hopes to graduate before it is asked to retire.

Iceberg, Omid and ShardingSphere submitted insufficient reports and will be asked to report next month.

A few mentors have been added and removed in various projects.

There were 3 IP clearances.

The incubator web site menu was reorganised to group similar content together, and further work was done on simplifying the language used on the incubator policy page. A few other pages were also improved.

The new disclaimer policy accepted by the board last month has received good feedback, and we've had a podling already make a release with it. The board asked for some updated documentation on the new disclaimer, and that was undertaken.

Some podlings are still struggling to get 3 +1 votes on their release by mentors and other IPMC votes are needed to make releases. However, those votes seem to be happing quite quickly with several IPMC members checking releases.

A new mentor guidance document is n the process of being created, so far not many mentors have contributed to this. Given the many years of experience over many mentors, it would be nice to see mentors contribute to this. This document would help future mentors and podling deal with everyday situations that come up that they may be unsure of how to deal with.

The IPMC consider dropping that ASF member can join just back asking. Looking at mentor it more than that mentors join this way go missing, other than those who are voted it. Some IPMC member didn't think this was a good idea, so the policy stands.

There was a long discussion on the requirement of IPMC vote on podling release which included several suggested changes to policy and new ideas. Consensus was not able to be reached on any changes, and the discussion has stalled. The main issue being that PMC votes are needed on releases and some IPMC members want to do away with IPMC votes on releases altogether. A new project was suggested as an experiment to try this out (exact details still to be worked out), but so far that has not happened. It was even suggested by a couple of IPMC members that a new incubator project be made.

It may be best to wait until we see the impact of the work in progress disclaimer before revisiting the IPMC vote situation.

There will be a Podling's Shark Tank at the upcoming ApacheCON North America and server talks on incubating subjects and projects.

ECharts is showing slow progress and thought they were ready to graduate when they were not. A face to face meeting with several experienced IPMC members has been organised at ApacheCon to get them back on the right track.

There was a discussion on the private on some podlings that probably should be retired.

IoTDB

IoTDB is a data store for managing large amounts of time series data such as timestamped data from IoT sensors in industrial applications.

IoTDB has been incubating since 2018-11-18.

Three most important unfinished issues to address before graduating:

1. Make the community (both the contributors and committers/PPMCs) more diverse and learn to discuss things on the mailing list.
2. More committers should know how to release a version.
3. Write more documentation to help new contributors.

Are there any issues that the IPMC or ASF Board need to be aware of?

No.

How has the community developed since the last report?

1. Some new contributors joined the community. E.g., PR#339 comes from a new contributor and it is really an interesting feature.
2. Some contributors (who are not committers yet) are more active than before. E.g., Boris Zhu and Jack Tsai.
3. More users began to report their issues. E.g., issue #171, #184 and #186.

As all the above contributions and contributors are not from the institutions/companies where initial committers are, we think it is a good signal that indicates more guys noticing the community.

How has the project developed since the last report?

1. IoTDB releases its first Apache version: v0.8.0 !
2. IoTDB is more stable and the performance is far better than before. However, the version is incompatible with previous version (which are released before IoTDB is denoted to ASF).
3. In v0.8.0, many issues are resolved (see release notes: http://iotdb.apache.org/#/Materials/Release%20Notes)

Myriad

Myriad enables co-existence of Apache Hadoop YARN and Apache Mesos together on the same cluster and allows dynamic resource allocations across both Hadoop and other applications running on the same physical data center infrastructure.

Myriad has been incubating since 2015-03-01.

Three most important unfinished issues to address before graduating:

1. Builds Apache Myriad releases regularly
2. Attract more users and contributors. Community growing.
3. Attract new mentors for helping the project towards the Apache Way.

Are there any issues that the IPMC or ASF Board need to be aware of?

We need new mentors, we have only one active mentor right now. We have to increase the community and we have to increase the number of mentors too in order to help us to address the Apache way with solid foundations.

How has the community developed since the last report?

We have four active committers (PPMCs) right now. A new committer since the last report. This is a small increment from the community growing point of view, but it helps regarding the minimal amount of PPMCs for achieving a release cycle with regularity.

How has the project developed since the last report?

The most important thing is the activity of creating new releases in a regular way. The Apache resources (project page, documentation page, …) are maintained and enhanced with new content. Taking into account the effort of rebooting the project (more than two years orphaned), the project is slowly addressing the right way, and we consider the project is successfully rebooted right now. This state allow us working towards attract new users and contributors in our humble opinion.

•  Initial setup
•  Working towards first release
•  Community building
•  Nearing graduation
•  Other: New important features focuses in production environments for attracting new users.

2019-08-02 New committer/PMC member Oscar Fernandez

Have your mentors been helpful and responsive?

We have only two mentors right now. One of the is for ever missing, and the other is ready for help when the project needs. So we have only one active mentor. This is an issue to address with the help of IPMC.

SAMOA has been incubating since 2014-12-15.

Three most important unfinished issues to address before graduating:

1. Revitalize the project by resuming development
2. Enlarge the user base and contributing community

Are there any issues that the IPMC or ASF Board need to be aware of?

None

How has the community developed since the last report?

• Mailing list activity:
• @dev: 12 messages

How has the project developed since the last report?

• Retirement has been suggested due to its very low activity
• To restart engagement, Corey Sterling has been elected as commiter in late August. With his help, we are preparing a new release of Apache SAMOA in early September. Corey Sterling has experience on open source software, as an example, he did the last release of MOA, an open source software non-distributed for data streams very related to SAMOA. He works at University of Waikato.

SDAP

SDAP is an integrated data analytic framework for Big Science problems.

SDAP has been incubating since 2017-10-22.

Three most important issues to address in the move towards graduation:

1. Make official SDAP (Incubating) Release
2. Improve/create user guide documentation
3. Improve committer participation

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be

aware of?

No.

How has the community developed since the last report?

We are continuing to attract new committers.

How has the project developed since the last report?

SDAP is still working towards its first release. Work towards a repeatable build pipeline has been started.

New functionality has been added to the Distributed Oceanographic Matchup Service (DOMS) and Extensible Data Gateway Environment (EDGE) components that allow for filtering in situ measurements by a standardized quality flag.

How would you assess the podling's maturity?

There are several deployments of SDAP actively being used and interest is high. However, active participation from project members is low. A push is needed to cross the t's and dot the i's in regards to meeting the requirements Apache has for releasing software so that we can claim a 1.0 version of SDAP.

IPMC/Shepherd notes:

Justin Mclean: The stats show don't mean much to people outside your project, please drop them from future reports and include commentary on how you project is growing instead. This report need a lot more detail for someone to get a good idea of where the project is at. A quick look at that stats, without explanation, suggests to me that this project is in trouble,. You have a large number of contributors, and outstanding pull request, but are not voting committers in. Please discuss with your mentors what the committer bar should be and what it means to be a committer.

Spot

Apache Spot is a platform for network telemetry built on an open data model and Apache Hadoop.

Spot has been incubating since 2016-09-23.

Three most important unfinished issues to address before graduating:

1. Revive community activity (Discussion in mailing lists, increase frequency of commits)
2. Create a new roadmap and release plan that will improve adoption.
3. Make it easier to contribute to the project (e.g. documentation, framework).

Are there any issues that the IPMC or ASF Board need to be aware of?

No

How has the community developed since the last report?

Unfortunately there has not been much more community activity. However, we are need of more committers as there are only a couple of active committers at this time. This creates a bottleneck which makes it hard for the community to grow in interest.

How has the project developed since the last report?

There are a series of PRs that have been evaluated for the SPOT-181 epic, and Spot website branch (asf-site) that are in the process of being merged. We have enough votes to merge, and have put out a request to committers to review so they can be auto-merged if possible, otherwise we will just manually merge them via cli.

Once those are merged, we will work on the plan to merge SPOT-181 into master so that the Open Data Model is consolidated into the main branch of our code.

We're also working on re-focusing the project release roadmap. Our first step will be to re-engage with the community to better understand how/where Spot is being used today, what features/enhancements would benefit the community best, and which committers (existing and potential) are interested in contributing to the roadmap and releases moving forward.

  Comments: While the project has previously been active, done several releases, and recruited PPMC and committers, it is now very quiet. For graduation it only needs a couple of maintenance releases of the remaining code-bases (or not include those in graduation). I suggest the project use the next reporting period to discuss retiring vs. graduation.

IPMC/Shepherd notes:

Justin Mclean: I'm a little confused if you want to graduate or retire.

Toree

Toree provides applications with a mechanism to interactively and remotely access Apache Spark.

Toree has been incubating since 2015-12-02.

Three most important unfinished issues to address before graduating:

1. Active community
2. Increase active contributors

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?

Toree will have a talk at ApacheCon Las Vegas where we will talk about its overall status and current functionality as well as try to attract more users and in particular contributors.

After the release of Toree 0.3.0 the community slowed down, mostly due to Toree being somewhat stable and running on top of Spark, where the public APIs in use are also stable.

The community needs to work on a release that supports Apache Spark 2.4.x and Scala 2.12.

Toree might be one of those low activity projects which have enough active PPMCs (see last ppmc voting thread), and we might start graduation talks based on these facts.

How has the project developed since the last report?

Very little activity on the last few months after the Toree 0.3.0 release, mostly around some compatibility issues with Spark 2.4.x and Scala 2.12.
