Sylvain Lebresne commented on CASSANDRA-5228:
---------------------------------------------
I suspect we'd rather make that automatic rather a nodetool command if
possible. In fact, we could do that for every compaction. Typically, when we
create the compaction iterator, we could skip sstables that can be dropped
fully (but still consider them as compacted).
We may also want to tweak slightly
AbstractCompactionStrategy.worthDroppingTombstones so it return yes if the
maxLocalDeletion time is less than gcBefore (though the current version should
work reasonably well already).
> Track maximum ttl and use to expire entire sstables
