The Cassandra Query Language (CQL)
==================================
This document describes the Cassandra Query Language (CQL) [#]_. Note that this document describes the last version of
the languages. However, the `changes <#changes>`_ section provides the diff between the different versions of CQL.
CQL offers a model close to SQL in the sense that data is put in *tables* containing *rows* of *columns*. For
that reason, when used in this document, these terms (tables, rows and columns) have the same definition than they have
in SQL.

been deprecated and remove) and differs from it in numerous ways.
