Yuki Morishita commented on CASSANDRA-7414:
-------------------------------------------
Hmm, the problem here is not clear to me. Is it that it will be never compacted
because compaction score changes when cleanup/sstable size change? I think if
we continue to flush SSTables, eventually levels are filled up and reach
compaction threshold.
Some comments to the patch:
* getOverlappingStarvedSSTables: you can pull calculating min/max boundary out
of the loop.
* getOverlappingStarvedSSTables: why don't just add sstable to
withStarvedCandidate instead of union set of 1 sstable.
> After cleanup we can end up with non-compacting high level sstables

> If we run cleanup (or increase sstable size) on a node with LCS, we could end
> up with a bunch of sstables in higher levels that are "never" compacted.
