| # Apache Calcite |
| |
| Apache Calcite is a dynamic data management framework. |
| |
| It contains many of the pieces that comprise a typical |
| database management system but omits the storage primitives. |
| It provides an industry standard SQL parser and validator, |
| a customisable optimizer with pluggable rules and cost functions, |
| logical and physical algebraic operators, various transformation |
| algorithms from SQL to algebra (and the opposite), and many |
| adapters for executing SQL queries over Cassandra, Druid, |
| Elasticsearch, MongoDB, Kafka, and others, with minimal |
| configuration. |
| |
| For more details, see the [home page](http://calcite.apache.org). |
| |
| The project uses [JIRA](https://issues.apache.org/jira/browse/CALCITE) |
| for issue tracking. For further information, please see the [JIRA accounts guide](https://calcite.apache.org/develop/#jira-accounts). |
