The Apache Calcite team is pleased to announce the release of Apache
Calcite 1.17.0.
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 four months after 1.16.0. It includes more than
90 resolved issues, comprising a large number of new features as
well as general improvements and bug-fixes. Among others:
- Implemented Babel SQL parser that accepts all SQL dialects.
- Added support for "CREATE TYPE" DDL.
- Migrated to low-level ES rest client as main transport.
