Alan Liang updated CASSANDRA-1610:
----------------------------------
Description:
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.
The goal of this ticket is to make compaction pluggable enough to support
compaction based on max timestamp ordering of the sstables while satisfying max
sstable size, min and max compaction thresholds. Another goal is to allow
expiration of sstables based on a timestamp.
