Incubator PMC report for June 2019

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

At the request of the board, this monthly report is in markdown so that it's easier to read. Some podlings struggled to get their content in the correct format.

There are presently 49 podlings incubating. During the month of May, podlings executed XX distinct releases. We added one new IPMC members and three IPMC members retired.

We have no new podlings this month. One project graduated last month Dubbo and a couple of other podlings are heading towards graduation in the next few months.

Milagro which failed to report twice, reported this month (to be confirmed) and is again trying to reboot themselves, they seem a bit more serious this time. Toree's report, also missing last month, did report. Podlings XX didn't submit a report and have been asked to do so next month.

There were no IP clearances.

** DRAFT **

The IPMC requires clarity from the board if podlings need to follow ASF's release policy and distribution policy while in incubation. This question has been previously asked and the answer was unclear or strongly suggested that podling releases must follow ASF policy. What is happening in practice is that the IPMC allows releases with minor issues to go ahead and assumes they will be fixed in a later release (before graduation) and stops releases with serious issues from going ahead. I don't think anyone thinks that allowing releases with minor issues is an incorrect approach. Serious problems, like including GPL software, including compiled code, or copyright violations, are currently seen as a reason not to approve a release, and about 1 in 5 podling releases have a problem like this. Historically there's been a few releases with serious issues that have got various VP approval to make a release on a one by one, once-off basis. Recently it has been suggested by several people (including ex board members and others) that serious issues should be allowed in a IPMC release, and those issues only need to be fixed before graduation. Does the board share this view? A couple of podlings have also asked that their releases with serious issues be allowed. The board of course can answer this (or choose not to) in any way it sees fit. It would help the IPMC and it's podlings if the answer was one of:

• IPMC releases must follow the ASF's release policy.
• IPMC releases are allowed to have minor issues, but no serious issues.
• IPMC releases are allowed to have minor issues, but any serious issue needs VP approval to make a release. (What is currently practiced).
• IPMC releases can contain serious issues and don't require VP approval (What some people / podlings are asking for). If the boards answer allows releases to contain serious issues can it also answer this. Does the ASF's legal shield cover people making release with serious issues?

** DRAFT **

A while back the IPMC identified all of the mentors that were missing, and not performing their duties, and ask them if they wanted to continue, most of them stood down from the IPMC. During this process, it was found there was a strong correlation between not signing off reports and missing mentors. Looking at the reports being signing off there are currently 13 possibly inactive mentors. This number is a massive improvement over the last time where we had over 70 inactive mentors and is a good indicator that mentors are more engaged.

Some of the incubator wiki pages were missed in the transfer and infra are looking into why.

Podlings were reminded that they to put their logos on http://www.apache.org/logos/ about 1/3 of them responded and added their logo.

A large number of Podlings didn't have their PPMC members or mentors signed up to their private list. A few mentors and podlings have corrected this and reminders to fix this situation has been sent to 20 podlings.

Testing the formatting

This is not really a project, just testing the formatting by creating for example a very long line 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789 that ends here.

Crail

Crail is a storage platform for sharing performance critical data in distributed data processing jobs at very high speed.

Crail has been incubating since 2017-11-01.

Three most important unfinished issues to address before graduating:

1. Community building: Increase on number of contributors and users.
2. Further increase project visibility by establishing a convincing use cases of Crail.
3. Make Crail better consumable / cooperate with other projects on Crail integration.

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?

• Apache Crail was presented at 2019 Strata data conference in San Francisco. The presentation is online available.
• We added one new blog posts to the projects Apache home page. It covers deployment options for tiered storage disaggregation.
• A paper on an Apache Crail based, unified ehpemeral data storage architecture got conditionally accepted at the USENIX ATC'19 Conference in July.
• The @ApacheCrail twitter account has now 164 followers. We use it to regularly tweet the availability of new blog posts, code releases etc.

How has the project developed since the last report?

• New CrailConfiguration API to allow setting Crail configuration dynamically instead of loading it from a file.
• NVMf tier: It is now possible to set Client host NQN to support restricted access on target side. If host NQN is not specified, a random UUID is still generated.
• Started design of fault tolerance/robustness extensions to Crail namenode implementation.
• Started integration of Crail as an ephemeral data store for serverless frameworks. Publicly discussed integration options at a presentation on 2019 OpenFabrics workshop.
• Continued native C++ implementation of Crail tailored to Machine Learning framework integration.

ShardingSphere

Sharding-Sphere is an ecosystem of transparent distributed database middleware, focusing on data sharding, distributed transaction and database orchestration.

ShardingSphere has been incubating since 2018-11-10.

Three most important unfinished issues to address before graduating:

1. Continuing to grow the community
2. Make several releases

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?

The community has been growing. Some volunteers take the issues and some contributors want to donate UI to ShardingSphere. We have finished the first apache release on 21 Apr.

How has the project developed since the last report?

There have a new landscape v0.1 release for ShardingSphere, to split core features and technical layers.

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?

After the release of Toree 0.3.0 the community slowed down, but we are starting to see asks for supporting Spark 2.4.x which requires releaseing Scala 2.12 artifacts and this should spark some community momentum.

Very little activity on the last three/four months after the Toree 0.3.0 release
