In 1.0, there is a mechanism by which these CFs are motivated to flush, when they fragment the commit log too much. https://issues.apache.org/jira/browse/CASSANDRA-2427 In 2.0, there is a re-introduction of the time based bound for memtables which allows you to automatically flush after a fixed time... but it is still a global setting. https://issues.apache.org/jira/browse/CASSANDRA-4237 memtable_flush_period_in_ms =Rob
