The Apache Calcite team is pleased to announce the release of Apache
Calcite 1.26.0.
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 a SQL parser and, as a sub-project, the Avatica JDBC driver.
This release comes about two months after 1.25.0 and includes more than 70
resolved issues, comprising a lot of new features and bug-fixes. Among
others, it is worth highlighting the following: SEARCH operator and Sarg
literal, PIVOT operator in SQL, spatial index based on Hilbert
space-filling curve, utility to visualize RelNode, and support for JDK 15
and Guava version 29.0-jre.
You can start using it in Maven by simply updating your dependency to:
<dependency>
<groupId>org.apache.calcite</groupId>
<artifactId>calcite-core</artifactId>
<version>1.26.0</version>
</dependency>
