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.
