Attached below is a draft of this month's board report. Please let me
know if you have any additions or corrections.
## 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.
## Issues:
There are no issues requiring board attention at this time
## Activity:
Development and mailing list activity is steady for both Calcite and its
Avatica sub-project.
We have been seeing a lot of new contributors open pull requests and
participating in our mailing lists to answer questions and partake in
discussions. This is most likely due to Calcite being increasingly
adopted as part of commercial offerings offered by cloud service
providers as well as being used to build internal tools. The increased
participation by new contributors is reflected in the 3 new committers
we have added to the project in the last 3 months.
In the last report, we mentioned that there were some issues with pull
requests not being reviewed in a timely manner. Over the last few
months, we have observed new contributors and non-committers reviewing
open pull requests in our repositories in conjunction with our existing
committers. This is a great improvement and we hope this will put us on
the path to stop PRs from getting too stale.
In terms of releases, Calcite 1.19.0 was released at the end of March
and includes numerous bug-fixes as well as extensive improvements in
JSON query support.
Finally, the Calcite website repository was moved to git. As a result of
this move, all of our source repositories are now using GitBox, enabling
new contributors to easily submit pull requests via Github.

Calcite and Avatica.
