Incubator PMC report for February 2020

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/February2020 There are presently 46 podlings incubating. In January, podlings executed 11 distinct releases. We added three new IPMC members and sixteen IPMC members retired. There was two requested IP clearance, one had an issue and the problem with last months IP clearance has been resolved. We have one new podling this month YuniKorn; another is under discussion AgensGraph. No projects graduated last month. Myriad has retired, and both Tamaya and Taverna are considering leaving the Incubator. At least one podling is heading towards graduation in the next few months.

Two podlings did not report and will be asked to report again next month; they include PageSpeed and Taverna. This is the second time Taverna has failed to report and looking on their list they are discussing retiring from the Incubator. PageSpeed reached out to say they will report next month.

It was noticed that a dozen of so podlings were missing multiple PPMC members signed up to their private mailing lists. Each podling was contacted, and just about all of them have corrected this. Three podlings MXNet, SDAP and Spot are still working on it.

Several IPMC members are not signed up to the IPMC private list and may not be providing the oversight needed by their role. A board proposal has been put forward to remove them from the IPMC.

These IPMC members have been emailed twice in the last month asking them to sign up. About 30% of the people identified have responded, and have signed up or asked to no longer be IPMC members. Most of them are ASF members, so even if they were removed, they could ask to join again.

A dozen inactive mentors were contacted offlist and asked if they want to continue in the role, several have responded they wish to step down, and a couple have done so.

The IPMC roster was also cleaned up with the removal of several people who had previously stood down or passed away.

TubeMQ is no longer having issues bootstrapping, but needed guidance with their report.

We were contacted by a researcher from the University of California to sign a letter of support for a project to study incubating projects. While the Incubator is supportive of research like this, some concerns were raised about the scope of the letter, and it was not signed.

Annotator

Annotator provides annotation enabling code for browsers, servers, and humans.

Annotator has been incubating since 2016-08-30.

Three most important unfinished issues to address before graduating:

1. Grow contributions outside the PPMC.
2. Establish release cadence.
3. Improve documentation, and in particular articulate a roadmap.

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

The podling missed reporting in January due to holiday disruptions and has been slow to make its first ASF release. The release machinery is all in place as of this month, and voting for the first release candidate should begin within the week.

How has the community developed since the last report?

The PPMC has been more actively communicating and plans to open up a weekly call to more directly engage early users.

How has the project developed since the last report?

The release machinery is in place, with Apache Rat being used to verify that licenses are in order. The PPMC is resolved to release the current state of the project and generate momentum from there.

How would you assess the podling's maturity?

Please feel free to add your own commentary.

•  Initial setup
•  Working towards first release
•  Community building
•  Nearing graduation
•  Other:

Date of last release:

Should begin voting within the week.

When were the last committers or PPMC members elected?

No new committers nor PPMC members have been added since the last report.

Have your mentors been helpful and responsive?

Mentors have been very helpful so far. They will be engaged around the initial release, to help ensure that everything is in order.

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

All the proper incubation disclaimers should be in the repository and on the website. The project is aware of no incidents of misuse of brand or trademark.

DataSketches

DataSketches is an open source, high-performance library of stochastic streaming algorithms commonly called "sketches" in the data sciences. Sketches are small, stateful programs that process massive data as a stream and can provide approximate answers, with mathematical guarantees, to computationally difficult queries orders-of-magnitude faster than traditional, exact methods.

DataSketches has been incubating since 2019-03-30.

Three most important unfinished issues to address before graduating:

1. Be more communicative and document our code changes more clearly.
2. We need to have more substantive discussions on dev@ especially about our growing TODO list and how we plan to address them -- create a roadmap as a guide for others to contribute.
3. Find / Attract new code committers outside Yahoo!

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?

We are presenting at more conferences which has attracted some interest. We are definitely getting more traffic on our forum, GitHub issues and email lists. We recently added two channels on the-asf@slack: #datasketches and #datasketches-dev. The traffic has been fairly low on Slack as well as the forum. We could do more to publicize the slack channels. I could be optimistic and believe the low traffic is due to the holidays -- or that the code just works :)

Nonetheless, the download traffic measured by repository.a.o has grown exponentially since our first Apache release on Sep 23. We are over 1000 unique IPs/ month and had a recent high of 22K downloads/ month. Bear in mind that this is all traffic that has migrated from the older, pre-Apache artifacts at com.yahoo.datasketches and is already higher than our peak downloads prior to Apache. These numbers also do not reflect any downloads of our Zip artifacts from a.o./dist (which includes our C++ artifacts) or other external download repositories (for example, specific to PostgreSQL).

How has the project developed since the last report?

Our releases are becoming easier, more polished and routine. Nonetheless, our website needs a lot of work (as mentioned above) and this will become our focus for the next month or so.

When were the last committers or PPMC members elected?

No new committers since April, 2019.

Have your mentors been helpful and responsive?

Yes. No open issues.

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

To the best of our knowledge, yes.

• Are 3rd parties respecting and correctly using the podlings name and brand? As far as we know, yes.

• If not what actions has the PPMC taken to correct this? We have not had to face this issue yet.

• Has the VP, Brand approved the project name? Yes, and it is clearly stated as such on http://incubator.apache.org/projects/datasketches.html

Doris

Doris is a MPP-based interactive SQL data warehousing for reporting and analysis.

Doris has been incubating since 2018-07-18.

Three most important unfinished issues to address before graduating:

1. Continue to build our community. It is glad to see that more developers joined us and became contributors. But we still need more leading developers to join the community who can participate in the discussion of Doris' road map, not just start-up members.
2. Improve the documents and website as well. Currently, most of documents are in Chinese and most of English docs are translated by machine. We are working on it.
3. The discussion on dev mail list is still very few. Most of discussion and decisions are still make in private or in GitHub issues. We should improve the utilization of mailing lists and discuss more public.

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?

Since the last report, we have added 21 contributors and 1 committer. There are currently 79 contributors and 15 committers.

More and more companies are considering choosing Doris as their solution, and more people are contributing to Doris. In the past three months, the number of contributors has increased from 58 to the current 79.

How has the project developed since the last report?

The community is working hard to improve the usability and functionality of the product so that more people can use Doris more easily to solve their problems. During this time, a total of 336 commits were merged and 333 issues were created.

Our new storage engine refactoring is almost coming to an end. After this work, some exciting features can be added, such as secondary index, etc.

ECharts

ECharts is a charting and data visualization library written in JavaScript.

ECharts has been incubating since 2018-01-18.

Three most important unfinished issues to address before graduating:

1. Status page ( https://incubator.apache.org/projects/echarts.html ) has not been updated and we are going to do this within a month.
2. Official Website: We have redirected echarts.baidu.com to echartsjs.com and put a banner in echartsjs.com stating that the official Website is echarts.apache.org but we still need to come to a conclusion about whether CDN still has a problem with the access in China. If so, we should probably make echartsjs.com as a mirror site with a clear specification about the main site. If not, we should redirect echartsjs.com to echarts.apache.org.
3. Currently the collaborator of echarts npm package is ecomfe and we should move it to echarts.

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?

More people from the community become contributors, either in the form of answering questions in the issues, fixing the document or making pull requests with the code. We did more public introduction about the community and welcome others to contribute and it did show some positive effects recently.

How has the project developed since the last report?

The monthly release became quite on time recently and in each release, we have several pull requests from the community.

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?

In the last month, our focus was on setting up some structures that help growing the community:

• Further people appeared on the mailing list expressing their interest to develop StreamPipes components
• We added issues in Jira that are targeted at new developers (marked with a newbie tag)
• We migrated the previously internal Wiki to Confluence and added developer information to lower the entry barrier to contribute
• Blog post on how to run StreamPipes on a Raspberry Pi, we now plan to publish blog posts at regular intervals
• Contact to sensor producer, and first integrations with their sensors, which should help growing the ecosystem
• Meeting with a manufacturing company to present StreamPipes and talk about cooperation possibilities
• We started to plan ApacheCon talks (also a joint talk together with Apache PLC4X)
• The number of Twitter followers has increased (currently at 103)
• The number of Github stars has increased (currently at 109)

How has the project developed since the last report?

• Successfully migrated complete development cycle to new GitHub and Docker Hub repositories
• Optimized containers to run on ARM architectures
• Implemented further algorithms to merge data streams and pre-process data for machine learning tasks
• Checking licences of the UI and adding checklist to Wiki
• Checking licenses of the backend and populated the LICENSE-binary file
• Currently, we are finishing a license review to properly create LICENSE and NOTICE files

In the next month, we plan to continue our work towards the first Apache release.

No new committers were elected beyond the initial committers. Two people mentioned on the mailing list that they might be willing to contribute to StreamPipes.

Have your mentors been helpful and responsive?

Our mentors are very responsive and provide good feedback. We discovered an issue that some mentors are not subscribed to the private mailing list and got in contact with them to fix this issue.

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

• We are currently preparing a new logo
• Currently, no issues are known related to brand misuse, but there are still some open issues concerning the transition to the ASF infrastructure (e.g., shutting down the old streampipes organization on Github to avoid confusion)
• We've started to research best-practices related to brand management (other ASF projects) and intend to add a section in the Confluence Wiki on brand management.

1. Gain more active contributors and committers
2. Decide how to ensure future development of Tamaya

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

Since we lack a lot of committers and contributors we started a discussion on the mailing list about the future of the project. One way might be to let the code return to Github instead of becoming a TLP

• it's an ongoing discussion with no decision yet.

No changes in the project.

Training

The Training project aims to develop resources which can be used for training purposes in various media formats, languages and for various Apache and non-Apache target projects.

Training has been incubating since 2019-02-21.

Three most important unfinished issues to address before graduating:

1. Promote the information about Apache Training Project with increased participation from community
2. Create a tutorial on how the tools provided by this project can be used to create own content
3. Review current policies around contribution review and releases to find a pragmatic compromise

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

• There currently is a lack of involvement by the PPMC in the project which caused stagnation in mailing list participation and overall project progress. The PPMC is currently taking steps to address this by focusing on promoting new committers and being more involved again.
• The current review and release process seems to be overly complex and scary and hampers contributions. Discussions around relaxing this are ongoing.

How has the community developed since the last report?

Activity on the dev list has declined since the last report, total number of posts was November 37, December 13, January (to be updated) 84.

How has the project developed since the last report?

• We have refactored the Maven structure to make adding new projects much easier by using an archetype, this should help make the project more accessible to a lot of people.
• ApacheCon themed templates are under development that will be available for speakers at future conferences
• An introductory Hadoop slide deck was contributed and is currently undergoing review.

How would you assess the podling's maturity?

There are currently some issues with this podling that we are working to address, we believe that the issues are not yet critical and can be turned around from within the community but want to make the board aware of this early on.

•  Initial setup
•  Working towards first release
•  Community building
•  Nearing graduation
•  Other:

Date of last release:

No new releases as ongoing discussions around the Pixabay license in LEGAL-479 have been blocking releases for months now.

When were the last committers or PPMC members elected?

Voting is currently ongoing to add a new committer to the projects roster.

Have your mentors been helpful and responsive?

Mentors have been responsive and helpful when reached out to.

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

The name search process has not yet been started, as there is still time to do that if and when graduation draws nearer. The PPMC is actively monitoring usage of the Podlings current name on other sites. The Podling is not directly affiliating with any sponsors donating content and presenting an independent image on the webpage.
