The Cassandra Query Language (CQL)

This document describes the Cassandra Query Language (CQL) version 3. Note that this document describes the last version of the language. However, the changes section provides the differences between the versions of CQL since version 3.0.

CQL offers a model similar to SQL. The data is stored in tables containing rows of columns. For that reason, when used in this document, these terms (tables, rows and columns) have the same definition that they have in SQL.
