Although Cassandra continues to support the Thrift RPC indefinitely, the CQL binary protocol described by the CQL Binary Protocol specification is a flexible alternative. The CQL binary protocol is a frame-based transport designed for CQL 3. To use the new binary protocol, change the start_native_transport option to true in the cassandra.yaml file (you can also turn start_rpc to false if you’re not going to use the thrift interface). An open source DataStax Java Driver and .NET Driver supports the CQL binary protocol. The driver documentation contains more information.
