The Apache Calcite team is pleased to announce the release of Apache
Calcite 1.13.0.
Calcite is a dynamic data management framework. Its cost-based
optimizer converts queries, represented in relational algebra, into
executable plans. Calcite supports many front-end languages and
back-end data engines, and includes an SQL parser and, as a
sub-project, the Avatica JDBC driver.
This release comes three months after 1.12.0. It includes more than 75
resolved issues, comprising a large number of new features as well as
general improvements and bug-fixes. Among others, it includes the
upgrade to Avatica 1.10.0, a new materialized view rewriting algorithm,
extensions for streaming queries, improvements for the Druid adapter,
and bug-fixes and general improvements for query planning.

<dependency>
<groupId>org.apache.calcite</groupId>
