June 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

See #10281 for example

more thoroughly the process of inviting new committers and PMC members[1].

We also began discussing adopting the sql parser into the DataFusion ASF

There are also several regional meetups planned: in San Francisco in June and
in China in July.

### DataFusion core
https://github.com/apache/datafusion

We made our first successful release as a new project, version 38.0.0

In addition to the work related to moving to a top-level project, the
community continues to work on making logical planning faster, making function
packages (i.e. UDFs) modular and easier to mix/match, and “de-parsing” logical
plan expressions back to SQL, and improve type coercion.

Recently there has been renewed interest in reading parquet files and creating
secondary indexes.


### Sub project: DataFusion Python
https://github.com/apache/datafusion-python

The DataFusion Python subproject has become more active since the last board
report with contributions from several contributors. Version 37 was released,
and version 38 is in the process of being released


### Sub project: DataFusion Comet
https://github.com/apache/datafusion-comet

The Comet subproject has had face to face sync meetings which are recorded[1].

## Community Health:

We have added several new committers and PMC members (see above) in the last
month, and we expect to continue to do so regularly. While it would always be
nice to have more bandwidth to devote to PMC activities, we are currently
doing well.

While most communications still happen through github, the mailing lists are
now fully active, as reflected in their metrics:

* dev@datafusion.apache.org had a big increase in traffic in the past quarter
  (71 emails compared to 0)
* github@datafusion.apache.org had a big increase in traffic in the past
  quarter (7685 emails compared to 0)
