## 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

There are currently 81 committers and 32 PMC members in this project.

## Community health
The community seems very actively engaged. We are closing issues faster
than they are opened; this is unusual. (A big credit is due to Zhen Chen,
who has been closing many old and new issues.)
Besides fixing many bugs and adding new features, we have seen some
significant contributions, such as a new query decorrelation algorithm
contributed by Silun Dong. I think the last year has seen a marked
improvement of the reliability of Calcite, especially in handling complex
queries.
- 142 JIRA tickets opened and 151 closed in the past quarter.
