Don't manually remove commit logs. Retention of commit logs should hopefully be because there are column familities that don't flush because they don't reach their thresholds in a long time. Decrease the expiry time for memtable flushing to make them flush more often. Flushing is relevant because only when a memtable is flushed can the commit log which contains the data being flushed, be removed by Cassandra. -- / Peter Schuller
