Attached below is a draft of this month's board report. I plan to submit it on October 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: There are currently 51 committers and 23 PMC members in this project. The Committer-to-PMC ratio is roughly 7:3. Community changes, past quarter: - Ruben Quesada Lopez was added to the PMC on 2020-08-10 - Rui Wang was added as committer on 2020-09-07 ## Project Activity: Avatica Go 5.0.0 was released on 2020-07-16. It is a major release of Avatica Go with a number of improvements and a breaking change affecting connection metadata. Worth mentioning the support for batching query string parameters in the DSN, allowing updates to the server to be executed once Close() is called on the prepared statement. Calcite 1.24.0 was released on 2020-07-24, including more than 80 resolved issues. Among those it’s worth highlighting some new features of the optimizer for more efficient search space pruning as well as the support of a new SQL dialect for Presto. Calcite 1.25.0 was released on 2020-08-22, with fewer but important features improving the parameterization of optimizer rules, adding support for new spatial functions, and interval expressions. The release also introduced a few breaking changes but so far the users seem to have embraced the changes. Members of the community gave talks at ApacheCon 2020, bringing to the surface Calcite through discussions about other projects. Although we didn’t have talks dedicated to Calcite, it is nice to receive mentions and witness the adoption of Calcite by other open source projects and people in Academia. ## Community Health: The overall activity in the community has slightly decreased in the past few months without this being worrisome. Releases occur often, the community is growing, and most of the time users' questions do not remain unanswered. The design discussions were fewer in the past quarter and people leading these efforts had quickly led them to consensus. As a result, we didn't have lengthy debates thus it's normal to see the activity of the dev@ and issues@ lists slightly decreased (5% and 9% accordingly). The number of closed issues and pull requests decreased by 19% which can be explained by the low number of active committers (~12 during this period) out of which the majority pushed mostly individual contributions. A small decrease in closed issues can be attributed to those opened after applying static code analysis frameworks on the project that remain as tasks for the next versions.
