Tyler Hobbs commented on CASSANDRA-6109:
----------------------------------------
By the way, it might be a good idea to push this to 2.1 or to disable it by
default in 2.0.x. It's a bit of a major change for a bugfix release this far
into 2.0.x.
> 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.)
