Hello,
Below you can find a draft of this quarter's board report. I plan to submit

Please let me know if you have any additions or corrections.
Best,

-------------------------------------------------
## Description:
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 2015-10-22 (10 years ago)
There are currently 78 committers and 32 PMC members in this project.
The Committer-to-PMC ratio is roughly 5:2.
Community changes, past quarter:
- No new PMC members. Last addition was Alessandro Solimando on 2025-05-01.
- No new committers. Last addition was Zhen Chen on 2025-05-19.
## Project Activity:
Avatica 1.27.0 was released on 2025-09-30, it contains dependency upgrades,
Gradle 8.14 and support for MySQL unsigned types. There were no Calcite
releases this quarter, but we have started the discussions towards Calcite
1.41.0, so it shall be released soon.
## Community Health:
The community continues on a "Super healthy" status. As usual during the
northern summer, there has been a slow-down in the general activity in the
last
three months, e.g. we have seen a decrease in the mailing lists traffic in
the
last quarter (18% decrease in dev, 26% decrease in issues). Nevertheless, we
have had a decent amount of Jira tickets opened (129) and closed (100) in
the
past three months.
