The Apache Calcite team is pleased to announce the release of
Apache Calcite 1.12.0.
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 the Avatica
JDBC driver.
In 2 1/2 months since 1.11, 29 contributors have resolved 95
issues. We now have JDK9 support, new file/web and Pig adapters,
syntax extensions for streaming queries, and planning improvements
for Druid and sub-queries.
You can start using it in Maven by simply updating your dependency
to:
<dependency>
<groupId>org.apache.calcite</groupId>
<artifactId>calcite-core</artifactId>
<version>1.12.0</version>
</dependency>
