Client Libraries and CQL Drivers

Client Application Libraries simplify using Cassandra by providing a more meaningful abstraction on top of the lower layer client drivers. CQL (Cassandra Query Language) is an SQL-like language for Cassandra. DataStax Enterprise and DataStax Community comes with a tarball package for CQL.
