Hello,
Below you can find a draft of this quarter's board report. I plan to submit
the final version next Monday (a bit earlier than usual because I'll be
traveling in the next weeks).
Please let me know if you have any additions or corrections.
Best,
Ruben

## 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 (9 years ago)
There are currently 77 committers and 30 PMC members in this project.

## Project Activity:
Apache Calcite 1.38.0 was released on 2025-03-16. It contained contributions
from 45 contributors, and resolved 209 issues. Highlights include the
support
of the VARIANT and UUID data types, the support of checked arithmetic, the
addition of an optimal join enumeration algorithm based on dynamic
programming
(DPhyp), new operators and data type support in Arrow adapter, enhanced SQL
compatibility with additional functions across Oracle, PostgreSQL, Hive,
Spark, and MSSQL.
Apache Avatica-Go 5.4.0 was released on 2025-03-05. It included dependency
updates and various minor improvements.
Apache Avatica 1.26.0 was released on 2025-02-24. It contained several bug
fixes, dependency upgrades and support for JDK 23 and Gradle 8.7.
A hybrid meetup was organized on 2025-02-20. 40+ people attended the event
in
person in Santa Clara, California; with 30+ people joining remotely. Four
talks were presented, describing various topics such as: Federated Query
Planning with Calcite and Substrait; Streaming, incremental, finite-memory
computations in SQL over unbounded streams; Revolutionizing Data Lakes: A
Dive
into Coral, the SQL Translation, Analysis, and Rewrite Engine; and
Optimizing
Common Table Expressions in Apache Hive with Calcite.
## Community Health:
The community continues on a "Super healthy" status. Looking at the metrics,
we have seen a slight increase (3� in traffic on the dev mailing list; and
a
significant increase in commits (54� and code contributors (27� ; which is
somehow expected considering that the previous quarter was rather "slow"
(probably due to the holiday season).
The number of reviewers have increased compared with previous quarters
(with a
more balanced distribution among the top reviewers), which is good news
because this is one area where our project particularly struggles
frequently.
