> In CASSANDRA-1608, I proposed some changes on how compaction works. I think it also makes
sense to allow the ability to have pluggable compaction per CF. There could be many types
of workloads where this makes sense. One example we had at Digg was to completely throw away
certain SSTables after N days.
> This ticket addresses making compaction pluggable only.
