> 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.
