Introduction to CQL commands

Shows the CQL command syntax and rules, and provides instruction on using CQL shell (cqlsh).

CQL is the primary language for managing database resources, such as keyspaces, tables, functions, aggregates, user defined types, roles, access permissions, insert, update, and query tables commands.

For production, DataStax supplies a number of drivers so that CQL statements and search commands can be passed from client to cluster and back.
