> 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.
