The [Apache Calcite PMC]({{ site.baseurl }}) is pleased to announce [Apache Calcite release 1.16.0]({{ site.baseurl }}/docs/history.html#v1-16-0).

This release comes three months after 1.15.0. It includes more than 80 resolved issues, comprising a large number of new features as well as general improvements and bug-fixes to Calcite core. Among others:

  • Calcite has been upgraded to use Avatica 1.11.0, which was recently released.
  • Moreover, a new adapter to read data from Apache Geode was added in this release. In addition, more progress has been made for the existing adapters, e.g., the Druid adapter can generate SCAN queries rather than SELECT queries for more efficient execution and it can push more work to Druid using its new expressions capabilities, and the JDBC adapter now supports the SQL dialect used by Jethro Data.
  • Finally, this release drops support for JDK 1.7 and support for Guava versions earlier than 19.
