Jonathan Ellis commented on CASSANDRA-5151:
-------------------------------------------
bq. However, we still need to fix conflict in opening CFS with the patch attached before.
(This was done in CASSANDRA-5350.)

> This is from discussion in CASSANDRA-5137. Currently we skip loading SSTables that are left over from incomplete compaction to not over-count counter, but the way we track compaction completion is not secure.
> One possible solution is to create system CF like:
> {code}
> create table compaction_log (
> id uuid primary key,
> inputs set<int>,
> outputs set<int>
> );
> {code}
> to track incomplete compaction.
