The Apache Calcite team is pleased to announce the release of Apache Calcite 1.10.0.
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 shortly after 1.9.0. It includes mainly bug fixes for the core and Druid adapter. For the latest, we fixed an important issue that prevented us from handling consistently time dimensions in different time zones. You can start using it in Maven by simply updating your dependency to: <dependency> <groupId>org.apache.calcite</groupId> <artifactId>calcite-core</artifactId> <version>1.10.0</version> </dependency> If you'd like to download the source release, you can find it here: http://www.apache.org/dyn/closer.cgi/calcite/apache-calcite-1.10.0/ You can read more about the release (including release notes) here: http://calcite.apache.org/news/2016/10/12/release-1.10.0/ We welcome your help and feedback.
