Legend

Description 

A DROP KEYSPACE statement results in the immediate, irreversible removal of a keyspace, including all tables and data contained in the keyspace. You can also use the alias DROP SCHEMA. If the keyspace does not exists, the statement will return an error unless IF EXISTS is used, in which case the operation is a no-op.

Apache Cassandra™ takes a snapshot of the keyspace before dropping it. In Cassandra 2.0.4 and earlier, the user was responsible for removing the snapshot manually.

Example 

DROP KEYSPACE MyTwitterClone;
