Jonathan Ellis commented on CASSANDRA-2735:
-------------------------------------------
I wonder if CASSANDRA-2498 (and CASSANDRA-2503) would help here. Since you get
some help at read time, I would imagine you wouldn't need to be so aggressive
at actual compactions, which should mitigate the extra I/O Alan mentions.
