> This is particularly useful in the scenario where you have a few CFs with a
> high volume of overwrite operations; increasing the memtable size/op count
> means that you can do the overwrite in memory before it ever hits disk. Once
> on disk compaction is much more work for the system.
> But, you don't want to give _all_ your CFs that high of a threshold because
> the memory is better used elsewhere, and because it makes commitlog replay
> unnecessarily painful.
