Best regards, Zhen Chen ---- Replied Message ---- | From | Mihai Budiu<[email protected]> | | Date | 1/8/2026 09:33 | | To | Apache Calcite dev list<[email protected]> | | Subject | Draft board report for 2025 Q4 | Here is a draft of the current quarter's board report. This needs to be submitted by Jan 14. Please let me know if you have any suggestions for improvement. Thank you, Mihai --------------------------------------- ## 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. ## Project Status: Current project status: ongoing (high activity) Issues for the board: none ## Membership Data: Apache Calcite was founded 2015-10-21 (10 years ago) There are currently 81 committers and 32 PMC members in this project. The Committer-to-PMC ratio is roughly 3:1. Community changes, past quarter: - No new PMC members. Last addition was Alessandro Solimando on 2025-04-30. - Silun Dong was added as committer on 2025-12-14 - Thomas Rebele was added as committer on 2025-12-19 - Yu Xu was added as committer on 2025-12-16 ## Project activity Recent releases: - Calcite 1.41.0 was released on 2025-11-01 - Avatica 1.27.0 was released on 2025-09-30 ## Community health The community seems very actively engaged. We are closing issues faster than they are opened; this is unusual. (A big credit is due to Zhen Chen, who has been closing many old and new issues.) Besides fixing many bugs and adding new features, we have seen some significant contributions, such as a new query decorrelation algorithm contributed by Silun Dong. I think the last year has seen a marked improvement of the reliability of Calcite, especially in handling complex queries. - 142 JIRA tickets opened and 151 closed in the past quarter. - [email protected] had a 6% increase in traffic in the past quarter (314 emails compared to 294). - [email protected] had a 23% increase in traffic in the past quarter (1493 emails compared to 1211).
