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. Clearly, the most important issue for us is to add more committers.
   From the Clutch and Podling Website reports, this is the last major issue for us.

   We have tried to encourage folks that ask questions or raise issues to get more involved, and we have one or two folks that have expressed interest in submitting PRs or even a new sketch. But, alas, none have followed through, yet.

   Developing sketch code is very tricky and understanding how these algorithms work, and the math and statistics behind them, is a hurdle for most people. Yet, we have been very clear that we are prepared to train someone to become a committer. All we ask is that the candidate be open to learning about these fascinating algorithms and committed to work with us. We could use some active help from our Mentors or from the Board to help us find someone that would find this work interesting.

   I am convinced that there are folks in the greater Apache community that would really enjoy working on this library, we just need to discover who they are!

2. Referring to last month's report, we have made progress in setting up TODO lists on our major sites: Java and C++. And we keep working away at these lists. We have also improved our Downloads page and brought it up to Apache standards. I don't feel these should be issues for graduation.

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

The issue mentioned above. We could use some help in finding someone who would find working in the sketching algorithms area really interesting and would want to work with us to become a committer.

How has the community developed since the last report?

We have been accepted to present at two conferences this Summer, the USPTO technology conference and the Spark & AI conference.

We also have interest from Apache Flink and Apache Impala to integrate sketches into their systems. There has also been interest from Apache Beam, but so far no action.

How has the project developed since the last report?

We have done a lot of work making the C++ code more robust and will likely have a major new release of the C++ library before this report is read by the Board. We also in the voting process for a new Java release that cleans up some licensing glitches and fixes a bug found by Druid.

Our activity on Slack has increased quite a bit with interesting queries from all over.

We also have done a lot of work on the website, adding content and improving navigation. The Community and Downloads pages are all new. Please have a look!

We continue to improve our release process with more guided scripts and fix issues as we discover them.

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. Redirecting echartsjs.com to echarts.apache.org. See reason in the next question.

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

https://echarts.apache.org/ recently changed to a different CDN as a work around for HTTPS CA expiration problem. (See https://issues.apache.org/jira/browse/INFRA-20185?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel ) The CDN change makes the website slow, at least in China as we tested. Our next step is to use echarts.apache.org as domain name and use echarts.cdn.apache.org as resource server. After fixing this problem, we will redirect echartsjs.com to echarts.apache.org so that the website redirection problem can be finally solved.

How has the community developed since the last report?

The community has been more active on the mailing list and pull requests. We have been working on encouraging the community to contribute in varied forms and it seems to take effect. We received 23 pull requests from non-committers since last report.

How has the project developed since the last report?

We release a new version since last report and is discussing and working on the next big version.

https://github.com/echarts-maps This GitHub user is creating ECharts related projects. We asked him to add notations stating that these are not official Apache ECharts (incubating) project. It has this description now: "All projects are NOT associated with official Apache ECharts (incubating) project and are independently maintained by chfw.". We also asked the author to add this notice to the readme of each projects but he has not finished this yet because there are many projects need to change. We are under communication with him about this.

• As far as we know the brand is respected by third parties. We-Amp mirrors the incubator site over at modpagespeed.com - but will work on transferring the domain name to the ASF this quarter.
• It's not known if the VP, brand has explicitly approved, so that is something we need to make sure about and resolve.

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?

Unfortunately, not much has happened since the last report in February. We did add one new committer but other than that there has been hardly any activity. While we'd like to blame the current situation in the world for this it wouldn't be a fair assessment as we had the same problem in the previous period.

We still believe the idea of the Training project is a good one and E-Mails are being responded to so the project is not dead. It's a lack of time and dedicated resources that is at least partly to blame for this situation. We hope that development will pick up again in the future.

How has the community developed since the last report?

Activity on the dev list has declined even more since the last report with a total number of posts of 34 (most of which are automatted reminders).

How has the project developed since the last report?

n/a

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.

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.

Tuweni has been incubating since 2019-03-25.

Three most important unfinished issues to address before graduating:

1. Finish export notice for cryptographic elements
2. Vote in a few more committers
3. Keep release pace and adoption

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

No issues to report at this time.

How has the community developed since the last report?

We are seeing a few contributions in the bug reports and pull requests offered on the repository. The project is starting to gain good traction.

We have seen adoption of the project downstream and a couple of fixes contributed as direct result.

How has the project developed since the last report?

The project reached 1.0.0, which was a big milestone. The roadmap is on Github and more accessible. The project is also using Github actions to help kick faster CI for pull requests.

How would you assess the podling's maturity?

Gordon Martin as committer on 2019-08-01.

Have your mentors been helpful and responsive?

1.0.0 took a long time to release, and it's mostly to blame on the difficulty to check the release bits. We will need to do better there.

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

Yes. At present, there are no issues nor concerns with the Tuweni mark. We do not anticipate any issues with the mark regarding graduation.
