Since its inception, the Cassandra Query Language (CQL) has grown and matured, resulting in the 3rd version of the language (CQL3) being finalized in Cassandra 1.2 and further improved in Cassandra 2.0. Compared to the legacy Thrift API, CQL3 aims at providing an API that is higher level, more user friendly, but still fully assumes the distributed nature of Cassandra and it's storage engine. This talk will present CQL3, describing the reasoning and goals behind the language as well as the language itself. We will also touch on CQL's relationship with Thrift and will present the CQL binary protocol that has been introduced in Cassandra 1.2. We will wrap up by discussing the future of CQL.
