September 2024 ASF Board Report

[alamb]

Is your feature request related to a problem or challenge?

Per https://whimsy.apache.org/roster/committee/datafusion the DataFusion ASF board report schedule is

March, June, September, December

Describe the solution you'd like

I would like to draft a board report for the ASF board meeting, ideally with community help.

The meetings are typically in the second or third week of the month

Describe alternatives you've considered

I plan to do this in the same style that worked well in Arrow (see an example from @andygrove
here https://lists.apache.org/thread/7w4mgy98qomc6drvj2fo81gvhq6p0boc) -- make a google doc (or issue) that people can add relevant content to and then the chair (me for the time being) submits it to the board

Additional context

No response

Due Wed Sep 11 2024 (in 22 days)

[alamb]

Draft document is https://docs.google.com/document/d/10MrrMHyfALB9Vpjtl-6abGWdNz6VLiWR9yI1a6Yl1aw/edit

I also sent a note to the mailing list as well, but it doesn't see it posted yet

[alamb]

This is due Wed Sep 11

According to our records, you are listed as the chair of DataFusion,
a committee that is due to submit a report by Wed Sep 11th
for the next ASF board meeting. This is an initial reminder to prepare a
report for DataFusion and submit it as described below.

[alamb]

I updated the doc https://docs.google.com/document/d/10MrrMHyfALB9Vpjtl-6abGWdNz6VLiWR9yI1a6Yl1aw/edit and plan to submit in the 11th.

Project Activity:

The project continues to be active with many PRs and issues opened and
closed per day.

We wrote two public blogs about our work: 1, 2 and DataFusion and systems built on it are being featured in high profile (for the Database world) venues such as the CMU Database Systems Seminar

We are working to adopt the sqlparser crate into the project as well

DataFusion core

https://github.com/apache/datafusion

We continue the monthly release cadence versions 40.0.0, 41.0.0 and are on track for version 42.0.0. The 41.0.0 release had almost 70 unique contributors.

We are currently focused on performance including for high cardinality aggregates and adding support for StringViewArrays. We completed a long running project to ensure all aggregate functions use the same API and are beginning the same project for window functions.

We have been discussing what features to include, and working to add LogicalTypes, as well as to create a more differentiated CLI experience. See the roadmap ticket for more details.

Sub project: DataFusion Python

https://github.com/apache/datafusion-python

The DataFusion Python project has received significant contributions recently to make the project more “Pythonic” and now has regular activity from maintainers. Tim Saucer has been added as a committer who focuses more heavily on datafusion-python.

Sub project: DataFusion Comet

https://github.com/apache/datafusion-comet

The Comet project is very active and recently released its initial 0.1.0
source release. Blog post: https://datafusion.apache.org/blog/2024/07/20/datafusion-comet-0.1.0/

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

• COMET-0.2.0 was released on 2024-08-28.
• 41.0.0 was released on 2024-08-11.
• PYTHON-39.0.0 was released on 2024-07-02.

• PYTHON-37.1.0 was released on 2024-05-13.
• 38.0.0 was released on 2024-05-10.

Community Health:

It is still hard to keep track of everything going on these, which is a good thing. While it is always a struggle to get enough code review capacity, the committers keep things going and the community helps each other out with reviews. We continue to actively grow our committer and PMC ranks.

There are currently four meetups planned: New York City, San Francisco (for the second time!) Belgrade, and Seattle.
