If your entire dataset in a keyspace or column family is deleted every [small time period], then maybe use TRUNCATE? Two caveats : 1) https://issues.apache.org/jira/browse/CASSANDRA-4655 - TRUNCATE will leave undelivered hints untouched until 1.2.6 2) TRUNCATE will create a snapshot unless you (unsafely!!!!!!! danger!!!!!!!!) disable this feature [1] Alternately, perhaps a datastore with immutable data files is not for you? :D =Rob [1] https://issues.apache.org/jira/browse/CASSANDRA-3710
