Description
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.
