Kevin Risden On Sun, Mar 1, 2020 at 5:34 AM Feng Zhu wrote: Thanks Julian. Let me make a brief introduction about the project. SuperSQL relies on both Calcite and Avatica (with inner branch). It aims to take the role as a unified entrance and middleware to connect various data platforms in Tencent, including RDBMS、ES、Hive、Flink、Spark、Presto、ClickHouse and some inner-built systems. They may be integrated as datasource or execution engine. As we are still busy on migrating massive workloads and supporting in-house business with SuperSQL, current now we do not have enough resources on public release (e.g., presentation, talks or posts). Therefore, it is not suprising that you wasn't aware of it before. Is it better to add the paragraph when we have website or an open-sourced version (maybe several months later)? Tencent's logo can be found in bottom right-hand corner in ( https://www.tencent.com/en-us/index.html). I think you can just pick up the english part (i.e. "Tencent").

If you would like to add it, please create a PR to add a paragraph to that page (no need for a JIRA case), and provide a link to a logo for Tencent that I can add to the picture.

It is my greate honor to be part of the community. Calcite is an excellent and promising project! I will do my best to contribute to the project.

Feng is an active contributor and has contributed a lot of code to some fairly complex parts of Calcite. He has been very helpful in discussions and reviews, especially around code generation, and his work is always of high quality. Feng, welcome, thank you for your contributions, and we look forward your further interactions with the community! If you wish, please feel free to tell us more about yourself and what you are working on. Stamatis (on behalf of the Apache Calcite PMC) -- Thanks, Xin

On 1/01/2020 9:18 pm, Stamatis Zampetakis wrote: Attached below is a draft of this month's board report. I plan to submit it on January 7. Please let me know if you have any additions or corrections. ## Description: Apache Calcite is a highly customizable framework for parsing and planning queries on data in a wide variety of formats. It allows database-like access, and in particular a SQL interface and advanced query optimization, for data not residing in a traditional database. Avatica is a sub-project within Calcite and provides a framework for building local and remote JDBC and ODBC database drivers. Avatica has an independent release schedule and its own repository. ## Issues: There are no issues requiring board attention. ## Membership Data: Apache Calcite was founded 2015-10-22 (4 years ago). There are currently 45 committers and 22 PMC members in this project. The Committer-to-PMC ratio is roughly 2:1. Community changes, past quarter: - Danny Chen was added to the PMC on 2019-10-30. - Haisheng Yuan was added to the PMC on 2019-11-11. - Stamatis Zampetakis was appointed as PMC chair on 2019-12-18, continuing the tradition of the project of rotating the chair every year. - No new committers. Last addition was Mohamed Mohsen on 2019-09-17. ## Project Activity: Calcite 1.21.0 was released in the middle of September, including more than 100 resolved issues and maintaining a release cadence of roughly one release per quarter. Calcite 1.22.0 is under preparation and is expected to be released inside January while at the moment contains more than 230 commits and 150 resolved issues. Avatica 1.16.0 was released in the middle of December, including numerous bug fixes and security improvements while the build system has been migrated from maven to gradle. The build and test infrastructure has been modernized for both Calcite and Avatica, with the migration from maven to gradle, JUnit4 to JUnit5, and the introduction of GitHub actions as part of the CI. The changes shall improve developers experience, code quality, and protect better against regressions. Members of the project participated in ApacheCon EU on October and Flink Forward Asia on November, representing the community, and presenting talks about Calcite. Finally, the Hazelcast system has decided to adopt Calcite for query planning. ## Community Health: Activity levels on mailing lists (37%), git (40%) and JIRA (opened 15%, closed 19%) have increased significantly in the last quarter. One reason is the modernization of the build and test infrastructure for both Calcite and Avatica, which triggered many discussions and follow-up tasks. Another reason, is the changes in the roster of the PMC and open discussions about the future of the project. Last but not least, is the involvement of new people in the community bringing up new challenges and ideas for improvements. The rates of pull requests being closed and merged on Github has increased by 16%, as we work to clear our backlog. Nevertheless, the number of open pull requests is still big since the number of committers who get involved in reviews is rather small. Furthermore, there are pull requests which are stale, work in progress, or proposals that make the numbers look even bigger. On the positive side every pull request receives comments within a couple of days after being submitted and there are many which get merged without too much effort showing that the project attracts skilled developers who may turn into committers quite soon.

{code:java}
$ ./mvnw install -DskipTests -Dcheckstyle.skip=true
