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.Hive uses Calcite for cost-based query optimization;Drill and Kylin use Calcite for SQL parsing and optimization;Samza and Storm use Calcite for streaming SQL.As of August 2016, Apex, Phoenix and Flink have projects under development that use Calcite."@en . . . . . . . . . . .
