LGTM. I also like the new entry that brings up the new JIRA accounts
that were created in this quarter.

+1 Thanks Mihai for preparing the report!
Some minor comments:
I think there is a formatting issue in this part:
- [email protected] had a 44% decrease in traffic in the past
- quarter (895 emails compared to 1575
which should be:
- [email protected] had a 44% decrease in traffic in the past
quarter (895 emails compared to 1575)
I'd personally keep the final top lists as a top3 or top5.
In the subject, I think it's better to use "2026 Q1" rather than "Spring",
to integrate also our contributors from the Southern Hemisphere :)
Best,
Ruben

here—the date I joined the PMC should be 2026-03-12.

Hello all,
Here is a draft of the report I have prepared for the Calcite board.
Please let me know if you have suggestions for improvement. The report has
to be submitted by April 8.
Thank you,
Mihai
## Description:
The mission of Calcite is the creation and maintenance of software
related to Dynamic data management framework
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 (11 years ago)
There are currently 82 committers and 33 PMC members in this project.
The Committer-to-PMC ratio is roughly 2.5:1.
Community changes, past quarter:

## Community health
The community seems very actively engaged. For the second quarter in
a row we have closed more issues faster than we have opened. (But
there is not much danger we'll run out of issues, don't worry.)
We have seen bug reports and contributions from a significant number
of new participants; e.g., we had 5 new JIRA accounts created.
- 110 JIRA tickets opened and 116 closed in the past quarter.
- [email protected] had a 34% decrease in traffic in the past
quarter (241 emails compared to 360).
