It is time to provide another board report. This is the start of our quarterly reports so after this we'll have only reports each quarter
I also think the primary reason for these reports is for the board to make sure the project is ok. The actual project details are more likely helpful for other members of the project than the board. With that being said, please feel free to provide your comments on the ticket[1], google doc[2] or reply to this email and I will incorporate them I plan to submit this to the board on September 11, 2024 Thanks, Andrew [1]: https://github.com/apache/datafusion/issues/10156 [2]: https://docs.google.com/document/d/10MrrMHyfALB9Vpjtl-6abGWdNz6VLiWR9yI1a6Yl1aw/edit ----- ## 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 (3 months ago) There are currently 33 committers and 13 PMC members in this project. The Committer-to-PMC ratio is roughly 9:4. Community changes, past month: - Mehmet Ozan Kabak was added to the PMC on 2024-06-12 - Ruihang Xia was added to the PMC on 2024-06-12 - Lewis Zhang was added as committer on 2024-06-14 ## Project Activity: The project continues to be quite active with many PRs and issues opened and closed per day. We started working on a project blog [1] (previously we used the arrow blog) and hope to have our first blog post as an independent project later this month. There was a well attended face to face meetup in San Francisco, CA USA in June [2]. We have one planned for Hangzhou, China in July[3]. There appears significant interest in these events and there are at least 2 more planned for September in New York, NY USA and in Belgrade, Serbia The community around DataFusion is growing too. For example, Spice AI has made an initial contribution of TableProviders to datafusion-contrib [4] for PostgreSQL, MySQL, DuckDB, and SQLite, enabling these data sources to be easily queried through DataFusion.

Some projects we have been working on recently involve adding support for more flexible use of Parquet files including indexing and extracting statistics. We are also working with the community to make extending SQL planning[2] easier and extending file format support[3], as well as fixing bugs found with a SQL fuzzer[4], and improving performance with StringView[5]. It has been nice to see several good examples of cross contributor/company collaboration such as [6] and [7]. We have also been making external presentations[1] [1]: https://github.com/apache/datafusion/issues/10969 [2]: https://github.com/apache/datafusion/issues/10534 [3]: https://github.com/apache/datafusion/pull/11060 [4]: https://github.com/apache/datafusion/issues/11030 [5]: https://github.com/apache/datafusion/issues/10918 [6]: https://github.com/apache/datafusion/pull/11203 [7]: https://github.com/apache/datafusion/issues/10534 ### Sub project: DataFusion Python https://github.com/apache/datafusion-python The DataFusion Python project continues to receive updates as new versions of the core DataFusion crate are released. There have also been some minor improvements to improve user experience. ### Sub project: DataFusion Comet https://github.com/apache/datafusion-comet The Comet project is very active and is working towards an initial 0.1.0 source release. Initial benchmark results were published to https://datafusion.apache.org/comet/contributor-guide/benchmarking.html. ### Sub project: DataFusion Ballista https://github.com/apache/datafusion-ballista https://github.com/apache/datafusion-ballista-python The Ballista subproject is not very actively maintained, but there have been some contributions recently to upgrade to more recent versions of the core DataFusion project. ### Recent Releases * PYTHON-39.0.0 was released on 2024-07-02. * 39.0.0 was released on 2024-06-10. * PYTHON-38.0.1 was released on 2024-05-30. * PYTHON-37.1.0 was released on 2024-05-13. * 38.0.0 was released on 2024-05-10. ## Community Health: Community health is good -- we recently hit the 600 total contributors mark according to Github. This number is partially inflated from initially being part of the Arrow mono repo but the trend is healthy non the less. It is hard to keep track of everything going on these days, which is a good thing. While it is always a struggle to get enough code review, the committers keep things going and the community helps each other out with reviews.
