Thanks for the summary Stamatis ~ Sigh to see the activity levels decrease, that may because some of the most committers/PMC has less activity recently, such as me, personally I’m really busy these days for my Flink work. But I have always try to check the daily mailing list and give some help if I have time (on the weekend).
I think things would be better and better, Calcite is a great project and we deserve to have more active committers in the future ~ Best, Danny Chan 在 2020年4月2日 +0800 AM6:08，Stamatis Zampetakis <[email protected]>，写道： > Attached below is a draft of this month's board report.

Last addition was Haisheng Yuan on 2019-11-11. > - Feng Zhu was added as committer on 2020-02-29 > > ## Project Activity: > 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. > > Calcite 1.22.0 was released at the beginning of March, including more than > 250 resolved issues including long-awaited features such as support of SQL > hints, important bug fixes in the core of the query planner, and many > changes in build and test infrastructure. This release was the biggest in > the history of the project and one of the most complicated to pull out due > to the big number of contributions. > > An introductory talk about query planning and Calcite was given at the > university of Cergy-Pontoise, Paris, France, in March. The audience was not > aware of the existence of the project which shows that we should organize > such events more often, at least in > Europe, if we want to expand our community. [Do we have something else to > add here?] > > Finally, we were informed that the SuperSQL project by Tencent uses Calcite > in order to provide a unified entrance to various data platforms such as > RDBMS, ElasticSearch, Hive, Flink, Spark, Presto, ClickHouse, etc. > > ## Community Health: > > Activity levels on mailing lists (-8%), git (-24%) and JIRA (opened -20%, > closed > -30%) have decreased in the first quarter of 2020. Most of the big changes > that started during the last quarter of 2019 (and initiated a lot of > activity) have > been finalized and incorporated in the release of Calcite 1.22.0, making > things > calmer in the community. The big decrease of closed issues in JIRA may be > explained by the frequency of releases that have slightly dropped. To the > above it is worth adding the period of holidays in December and January > that in general slows things down. > > Following the decreased activity in the lists, git, and JIRA it is normal > to see > the activity rates on pull requests drop (-20% opened, -31% closed) more or > less > for the same reasons. Although our backlog keeps increasing (~174 open > pullvrequests), the community is very reactive commenting and reviewing > almost every contribution.
