This section is a brief introduction to CQL 3 on Cassandra 1.1.x. We will see queries and discuss options available. For more formal query definitions, please refer to the Cassandra CQL 3 documentation that is appropriate for the Cassandra version that you are using. One of the good sources for this is the Apache CQL 3 documentation and the DataStax Cassandra documentation. Most of the queries that are mentioned here should work in 1.1.x as well as in 1.2.x versions, but the queries are not tested against 1.2.x and further versions.
