Incubator PMC report for March 2021

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

There are presently 37 podlings incubating. In February, podlings executed 5 distinct releases. We added no new IPMC members, and none retired. There was one IP clearance in February, and there was one new podling, EventMesh. Ratis and Daffodil graduated last month.

This month we were missing reports from Hivemall, Livy, PageSpeed, Spot, Toree, Weex. Toree has missed more than one report in a row, and the IPMC will take a roll call. NLPCraft will be asked to report again due to a minimal report. SAMOA has been retired and Weex will be retired shortly. Livy failed to report despite a recent roll call that received 3 PPMC member reponses. Currently, Brpc and Marvin-AI do not have signoff by mentors and will also be asked to report next month if they don't get signoff.

A vote to remove BlueMarlin from the Incubator was taken. This caused some action on the project's part, and they have moved communication to the dev list and the code to the ASF repository. Currently, they will be allowed to continue in the Incubator.

MXNet still has several trademark and branding issues that need to be resolved. MXNet is having trouble getting its mentors or IPMC members to vote on its releases. This is possible due to continuing issues and bandwidth required when dealing with this project.

A new proposal LXDB is under discussion.

Some retired podlings need some cleanup and be correctly retired, so the public is aware of this. Some of the old release directories were removed.

Most discussions on the mailing list were around releases, new project proposal, graduations and finding new mentors.

Three most important unfinished issues to address before graduating:

1. Vote in a few more committers.
2. We requested a space on Apache Docker Hub but still waiting for that. We have AGE images but need to have them on the Apache docker hub.
3. Need to create a home page for Apache AGE on confluence.

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?

1. We have more contributors working on the project.
2. More discussions from new contributors on building other tools such as drivers for the project and add to its ecosystem.

Hop

Hop is short for the Hop Orchestration Platform. Written completely in Java it aims to provide a wide range of data orchestration tools, including a visual development environment, servers, metadata analysis, auditing services and so on. As a platform, Hop also wants to be a reusable library so that it can be easily reused by other software.

Hop has been incubating since 2020-09-24.

Three most important unfinished issues to address before graduating:

1. create a first full release (including binaries)
2. trademark (re)search
3. HOP-2469: Ensure that Hop complies with ASF encryption policy

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?

Community and interactivity on social media continues to grow (LinkedIn: 400+, Twitter: 325+, Youtube: 80). We're actively engaging in discussions on the dev mailing lists. There's still some room for improvement, but we're convinced this will grow over time and as the community continues to grow.

How has the project developed since the last report?

0.60 was released as source only. This allowed/forced us to tackle the most pressing licensing issues. We're working towards the 0.70 release. Since this release will include binaries, we're cleaning up any remaining license issues with dependencies and the notice, license and other files. Development continues at a fast pace. We're starting to see a steady stream of contributions from a variety of community members.

Have your mentors been helpful and responsive?

We've been able to get all the help and answers we needed. Julian Hyde has been especially helpful since the start of the incubation process by pointing out risks, providing guidance in adopting "The Apache Way" and being an overall great support to the Hop team.

Is the PPMC managing the podling's brand / trademarks?

The "Apache Hop" brand name seems to be used correctly, we are not aware of any violations. Third parties may not always use the "(Incubating)" suffix sufficiently, but since this is mentioned extensively in our own communication, website and social media accounts, we consider this to be a minor issue. Trademark search still needs to be done, but is high on the PPMC's priority list.

  Comments: Hop are doing great. After some prodding from the mentors, they have moved discussions away from chat and onto the dev list. They flag themselves as "nearing graduation" and I concur. Note that we need some help from Justin to register the project's use of encryption.
•  (hop) Maximilian Michels
  Comments: The project is doing well. More and more blockers for graudation got resolved, e.g. licensing headers and the first release. Let's keep up the good work!

Dave Fisher: Its great to see an active and engaging community on the dev list. I think that the PPMC does need to grow in numbers some prior to graduation.

Our small community size means responding to specific requests can take time so building community numbers is still important. Getting another committer on board could really help.

IPMC/Shepherd notes:

Wayang

Wayang is a cross-platform data processing system that aims at decoupling the business logic of data analytics applications from concrete data processing platforms, such as Apache Flink or Apache Spark. Hence, it tames the complexity that arises from the "Cambrian explosion" of novel data processing platforms that we currently witness.

Wayang has been incubating since 2020-12-16.

Three most important unfinished issues to address before graduating:

1. Educate the new PPMCs to be able to do Apache releases
2. Do our first Apache release
3. Grow the community

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

Until the moment of this report it was created and didn't have any issue, because all the important issues got solved.

How has the community developed since the last report?

In the last month the community did a meeting where they created the most important point to be focused on. The main focus points are the creation of a Python API, SQL API and maintenance on the Core to be enabled to support the new API's. The protocol of that meeting can be found it on dev@ list

Additional to that the community is searching for more developers that can be part of it.

Also during the last month the issue with the software grant got solved and we are waiting for the document to get signed.

How has the project developed since the last report?

The project has moved the codebase to Apache's Git repos as well as successfully setup the CI jobs. Also the Website is now up and running.

The team is finishing the process of renaming the project from Rheem to Wayang, and is important to review that everything is placed in the right spot.
