Björn Hegerfors commented on CASSANDRA-10276:
---------------------------------------------
I have one comment on this patch. If for some reason the STCS won't find
something to compact even though bucket.size() > maxThreshold (sounds unlikely
with default STCS options), then just skipping that window might render that
window uncompacted for all eternity. IMO, rather than trying the next window,
as in the latest commit, why not just return the maxThreshold smallest SSTables
from the bucket?
> With DTCS, do STCS in windows if more than max_threshold sstables
