Hello, The DataFusion ASF board report[1] is due in 2 days (2025-12-10). I have made a draft at [2] and copy/pasted below. If you have anything to add please let me know by responding to this email or adding comments directly in the document.
[1]: https://github.com/apache/datafusion/issues/17506 [2]: https://docs.google.com/document/d/1UNZNLOGm4FiJ8l_8q6tIJkvyD2nmSpDi4SmtOAIU8qc/ Andrew ------- 2025-12-10 DataFusion ASF Board Report https://github.com/apache/datafusion/issues/17506 DataFusion PMC Chair Note: Please add any relevant comments / content to this document. I (Andrew Lamb) will submit to the ASF board on Wed Dec 10, 2025 (about one week prior to the scheduled board meeting). The format of this report and the metrics are from https://reporter.apache.org/wizard/?datafusion The rationale and process for this report: https://www.apache.org/foundation/board/reporting Past examples: 2025-09-10 DataFusion ASF Board Report ## Description: The mission of Apache DataFusion is the creation and maintenance of software related to an extensible query engine ## Project Status: Current project status: New + Ongoing (high activity) Issues for the board: None ## Membership Data: Apache DataFusion was founded 2024-04-16 (2 years ago) There are currently 54 committers and 20 PMC members in this project. The Committer-to-PMC ratio is roughly 7:3. Community changes, past quarter: - Jeffrey Vo was added to the PMC on 2025-11-23 - Yongting You was added to the PMC on 2025-11-23 - Gabriel Musat was added as committer on 2025-10-31 - Raz Luvaton was added as committer on 2025-10-01 - Zhen Wang was added as committer on 2025-10-02 - Yoav Cohen was added as committer on 2025-09-17 ## Project Activity: Note that almost all communication for DataFusion and its subprojects happens on github and so our dev mailing list traffic is fairly light. ### DataFusion core https://github.com/apache/datafusion 51.0.0 was released on 2025-11-19. 50.3.0 was released on 2025-10-24. 50.1.0 was released on 2025-10-02. 50.0.0 was released on 2025-09-16. The most recent release (~ 2 months of contributions) had 128 distinct contributors, which we think is a record and shows the project is able to attract and sustain a large community. Development is now largely focused on more advanced optimizations, and we have been able to attract a significant amount of engineering investment from the community We have gotten better about writing about our releases externally, including several blogs https://datafusion.apache.org/blog/2025/11/25/datafusion-51.0.0 https://datafusion.apache.org/blog/2025/09/29/datafusion-50.0.0 https://datafusion.apache.org/blog/2025/09/21/custom-types-using-metadata https://datafusion.apache.org/blog/2025/09/10/dynamic-filters We have also held several in person meetups in various locations, which have been successful in bringing together contributors. Finally, as always, the biggest bottleneck for increasing project velocity is reviewer capacity. The rise of AI powered coding assistants has made this bottleneck more acute as it makes it easier to create large PRs. The community has written up [guidelines] for AI assisted contributions which seems to have improved the overall PR quality.

DATAFUSION-PYTHON-50.0.0 was released on 2025-09-23. ### Sub project: DataFusion Comet COMET-0.12.0 was released on 2025-12-01. COMET-0.10.1 was released on 2025-10-06. COMET-0.10.0 was released on 2025-09-16. https://github.com/apache/datafusion-comet You can read about the recent happenings in Comet in the blogs: https://datafusion.apache.org/blog/2025/12/04/datafusion-comet-0.12.0 https://datafusion.apache.org/blog/2025/10/21/datafusion-comet-0.11.0 https://datafusion.apache.org/blog/2025/09/16/datafusion-comet-0.10.0 ### Sub project: DataFusion Ballista BALLISTA-50.0.0 was released on 2025-11-22. BALLISTA-49.0.0 was released on 2025-10-06. https://github.com/apache/datafusion-ballista ### Sub project: sqlparser-rs SQLPARSER-0.59.0 was released on 2025-09-24. SQLPARSER-0.60.0 was released on 2025-12-07. https://github.com/apache/datafusion-sqlparser-rs Ifeanyi Ubah (iffyio) continues to review most PRs in this repo. We added a new committer Yoav Cohen focused on sqlparser in an attempt to increase the review bandwidth available. ## Community Health: While we as always struggle with code review capacity, we have many active committers, and the community in general helps each other out with reviews. We continue to actively grow our committer and PMC ranks. We continue to merge multiple PRs a day from multiple committers and have contributions from a wide variety of individuals with a wide variety of employers.
