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/December2019

There are presently 45 podlings incubating. In December, podlings executed XX distinct releases. We added no new IPMC members and no IPMC members retired. There were one IP clearances.

We have one new podling this month StreamPipes; other is under discussion NuttX and two others a possibility. No projects graduated last month. Omin and Tephra exited the Incubator and became sub-projects of Phoenix. BatchEE is trying to complete becoming a subproject of Geronimo. At least one podling is heading towards graduation in the next few months. Podlings Daffodil, Marvin-AI and Warble did not submit reports and will be asked to report again next month.

Weex is actively working on its branding issues mentioned last month.

Further work was done on cleaning up the incubator web site, including the cookbook.

Podlings, have continued to use the new disclaimer policy, and this seems to be working well. TVM asked the Incubator to review a release candidate before making a release, and several issues were identified and fixed. PageSpeed, which joined the Incubator in October 2017, also put its first release up for a vote. A couple of releases needed IPMC prodding to get votes, but most were quickly voted on.

Some statistics were generated, showing how many project enter and leave and how long they stay in incubating to see if any trends were visible. While the overall trend is up, there has been a decrease in podlings joining the Incubator in the last couple of years. There may be a number of reasons for this, including the outside perception of the ASF. It is likely that the carrying capacity of the Incubator had been exceeded in years before this. There have been 315 projects helped by the Incubator, and 77% of them have graduated, most spend 1 1/2 years in incubation. There's been more than a 1000 mentors.

The Incubator release area was cleaned up and old releases from retired and graduated projects removed.

A new branding/trademark question was added the podling report and the podling proposal as a few podling have not realised the importance of this.

A new top level project called Petri, was approved by the board. It's goal is to help external projects go straight to TLP, not using the Incubating process.

MesaTEE

MesaTEE is the next-gen solution to enable general computing service for security-critical scenarios. It will allow even the most sensitive data to be securely processed to enable offshore businesses without leakage.

MesaTEE has been incubating since 2019-08-19.

Three most important unfinished issues to address before graduating:

1. Finish the initial setup for MesaTEE and its sub-repos.
2. Choose a suitable name for MesaTEE and rename the repos.
3. Make the access control mechanism and RPC framework more scalable and ergonomic.

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

Regarding to the CI system, we do have some problem with migrating the webhooks. MesaTEE definitely requires CI runs on customized hardware. However, the Apache INFRA team is pretty conservative on adopting novel CI systems which support customized hardware and self-hosted agent, such as Github Action, Drone etc. We observed that Apache projects depending on CI running on customized hardware, such as incubator-tvm, experienced difficulty to migrate its webhooks and was challenged several times on the reason of using customized hardware in CI. Besides, we observed that Apache Spark is using Github Action, while we are blocked on it (see INFRA-19381).

The bootstrapping process seems slow due to the above problem. We have a temporary workaround to use our Drone CI system. It leverages a sync bot which automatically sync up incubator-mesatee and a testing fork and triggers the webook of the testing fork. For management, we force the developers to put the link of CI status for each PR in their PR message. It works, but we really desire the integration to new CI and self-hosted CI agents.

For the renaming, we found a new name "Teaclave" which is not used anywhere.

How has the community developed since the last report?

MesaTEE has one more contributor this month, and merged 50+ PRs from 13 contributors.

How has the project developed since the last report?

We implemented the new access control system in MesaPy, and merged into MesaTEE. The new access control system is much more powerful and flexible than traditional user/role/group based access control system, and is memory-safe and trusted with the help of MesaPy and MesaTEE.

We improved the MesaTEE infrastructure to make it k8s-friendly. We refactored parts of the MesaTEE system and are doing on others.

We improved the build system. We deprecated the old-fashioned Makefile, and only kept the cmake system.

We figured out a temporary solution for integrating the Drone CI system and self-hosted agents by syncing up incubator-mesatee and testing fork, and triggering tests on the testing fork.

We are improving the built-in RPC framework to use prost to automatically generate Rust source codes from protobuf's protocol definitions.

We fixed a couple of bugs reported from the open source community.

SAMOA

SAMOA provides a collection of distributed streaming algorithms for the most common data mining and machine learning tasks such as classification, clustering, and regression, as well as programming abstractions to develop new algorithms that run on top of distributed stream processing engines (DSPEs). It features a pluggable architecture that allows it to run on several DSPEs such as Apache Storm, Apache S4, and Apache Samza.

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?

Nothing important. It took more than 2 months to create the account of Corey Sterling, as it seems that some things are still done manually, and there was a mistake with his email address. Finally, we could solve it out.

Have your mentors been helpful and responsive?

Mentors are responsive and helpful. Things tend to be on the right way.

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

At present, there are still some brand and trademarks problems. APISIX was the name of Apache APISIX before entering the incubator, so the search results of APISIX currently obtained through the search engine actually belongs to Apache APISIX and are completely controllable.

ShardingSphere

ShardingSphere 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. Clear Brand issues with other ecosystem projects.
2. Further ASF culture and processes.
3. Make more apache releases.

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

No. Right now, the brand issues are under control, so we think board or IPMC may do not need do any actions for now.

There are still several related project on GitHub org in ShardingSphere ecosystem, before or during project joined the ASF incubator, such as extension modules, extension module examples and acceptance test are not in Apache repo. We have already moved some extension modules into Apache repo, and plan to transfer all of them soon.

How has the community developed since the last report?

1. Ya Li, Zhiyi Yan have been voted and joined as committer.
2. There are 89 people to contribute codes to the main repo, there are 15 new contributors during last report. We are happy to see the community are growing up.
3. Over 100 companies have confirmed they are using ShardingSphere through issue report, and show at powered-by page[1]. Individuals from different companies and communities have provided some patches to feed back ShardingSphere community.
4. Share a topic for Apache way and how to join ShardingSphere community in Apache meetup at Tsinghua University.
5. Finish Podling Maturity Assessment for ShardingSphere[2].
6. Plan to establish a co-meetup with Apache DolphinScheduler(incubator) in Beijing at Dec 8th.

•  (shardingsphere) Willem Ning Jiang Comments: Shardingsphere made a very good progress of growing the community, I think it's time to consider the graduation.
•  (shardingsphere) Von Gosling Comments: developer community is very active in github issues and pr. IMO, if we could take brand / trademarks well in the next, it would be nice to call for graduation.

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?

There are community members that have reached out and are interested in contributing, but there are only a couple of active committers at this time. Currently the main hurdle for new contributors is the amount of effort required today to deploy Spot and build development environments.

How has the project developed since the last report?

Open PRs with sufficient votes against the master branch and SPOT-181 epic have been merged. There's also been a substantial amount of work to categorize all of the open JIRAs into a Project board on Github to help the community more easily triage high priority issues, organize feature enhancements into future epics, clean-up closed tickets, and also group issues that require more information from the community before taking action. Additionally there's been some work to clean-up the asf-site branch, and minor updates (PRs are being pushed soon). There's a larger project to re-organize the asf-site to make it easier for the community to update and add new pages, but that hasn't started yet.

The project with the most priority going forward is to make Spot easier to deploy. There's a large learning curve for deploying Spot today, which makes it difficult for both users and committers to be successful when standing up Spot, using certain features, testing, and making contributions back into the project. Using Cloudbreak to stand-up an environment and deploying Spot as an Ambari package will help lower the barriers to entry for new and existing users and contributors alike. We expect during this project that we'll also uncover a number of deployment issues and incompatibilities along the way and by resolving these will also help bring confidence to users that this new deployment pattern will be better tested and reliable.

StreamPipes

StreamPipes is a self-service (Industrial) IoT toolbox to enable non- technical users to connect, analyze and explore (Industrial) IoT data streams.

StreamPipes has been incubating since 2019-11-11.

Three most important unfinished issues to address before graduating:

1. Finish the initial setup
2. Make a first Apache release
3. Grow the community

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

There are no issues right now.

How has the community developed since the last report?

All initial committers have subscribed to the new mailing list. We started to spread the project on Twitter and other channels to reach more potential community members, but currently, the main priority is to move the project infrastructure to Apache. There was also one event focused on extending the developer base:

• We gave a talk at a meetup on "Self-Service IoT Data Analytics with StreamPipes" (~70 participants)

How has the project developed since the last report?

This is the first report after StreamPipes joined the incubator on November 11th. Most work during the last month was focused around setting up StreamPipes and doing some legal paperwork to transition StreamPipes to Apache:

• Creation of mailing lists
• Setting up the new StreamPipes Jira
• We made a last pre-Apache release and started to refactor our code (restructuring the code base to reflect the new repository structure)
• The website and documentation is already moved to Apache Git repositories, and a draft is online at streampipes.apache.org, however, we need to wait to "announce" the web page and forward traffic from the existing domains untilthe Git repos are all transferred
• All initial committers have signed and submitted their ICLAs
• FZI has submitted a CCLA and donated the initial code base to Apache
• Right now, we are waiting to transfer our existing Git repos from the streampipes organization to the Apache organization on Github
• We are also waiting to get admin access to the StreamPipes instance on Jira to import existing issues to the new issue tracker

When were the last committers or PPMC members elected?

No new committers were elected beyond the initial committers. We'll focus on attracting new committers once the initial setup is finished.

Have your mentors been helpful and responsive?

We would really like to thank our mentors. Chris was very helpful and responsive in setting up the infrastructure, and all questions we had on the mailing list were answered immediately by our mentors.

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

• We initiated an initial podling name search and created a ticket to get the name approved in Jira (November 25th).
• The name "Apache StreamPipes" got approved by VP Brand Management on December, 12th
