sankalp kohli commented on CASSANDRA-6216:
------------------------------------------
Instead of sorting all sstables in a level by token and iterating over them,
should we not pick those sstables which have the largest overlapping with
sstables in the higer level. Though this might cause starvation to some
sstables as they wont get a chance to compact. May be a mix of both will work
better.
> Level Compaction should persist last compacted key per level

> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: sankalp kohli
> Priority: Minor
>
> Level compaction does not persist the last compacted key per level. This is
> important for higher levels.
> The sstables with higher token and in higher levels wont get a chance to
> compact as the last compacted key will get reset after a restart.
