https://issues.apache.org/jira/browse/CASSANDRA-2816 (follow links to other jiras) https://issues.apache.org/jira/browse/CASSANDRA-2699 And yes to the one who asked: 'cleanup' only removes data that is not supposed to be on the node; repair transferes data that *should* be on the node, so only a compaction will cut down the size after a repair induced spike of load (data size). -- / Peter Schuller (@scode on twitter)
