Jonathan Ellis commented on CASSANDRA-6109:
-------------------------------------------
Looks reasonable.
- Can you make the actual drop-from-bucket a strategy option?
- Can you add a test that exercises prepBuckets to STCSTest, a la the
getBuckets test?
> Consider coldness in STCS compaction

> I see two options:
> # Don't compact cold sstables at all
> # Compact cold sstables only if there is nothing more important to compact
> The latter is better if you have cold data that may become hot again... but
> it's confusing if you have a workload such that you can't keep up with *all*
> compaction, but you can keep up with hot sstable. (Compaction backlog stat
> becomes useless since we fall increasingly behind.)
