Apache Calcite is an open source framework for building databases and data management systems. It includes a SQL parser, an API for building expressions in relational algebra, and a query planning engine. As a framework, Calcite does not store its own data or metadata, but instead allows external data and metadata to be accessed by means of plug-ins.
Several other Apache projects use Calcite.[3] Hive uses Calcite for cost-based query optimization;[4] Drill and Kylin use Calcite for SQL parsing and optimization; Samza and Storm use Calcite for streaming SQL. As of August 2016[update], Apex, Phoenix and Flink have projects under development that use Calcite.
