The API to Cassandra is CQL, the Cassandra Query Language. To use CQL, you will need to connect to the cluster, which can be done:
cqlsh is a command line shell for interacting with Cassandra through CQL. It is shipped with every Cassandra package, and can be found in the bin/ directory alongside the cassandra executable. It connects to the single node specified on the command line. For example:
$ bin/cqlsh localhost Connected to Test Cluster at localhost:9042. [cqlsh 5.0.1 | Cassandra 3.8 | CQL spec 3.4.2 | Native protocol v4] Use HELP for help. cqlsh> SELECT cluster_name, listen_address FROM system.local; cluster_name | listen_address --------------+---------------- Test Cluster | 127.0.0.1 (1 rows) cqlsh>
See the cqlsh section for full documentation.
