Jonathan Ellis commented on CASSANDRA-3050:
-------------------------------------------
Hmm. I guess we could have the cache provider include a sizeInMemory method?
For serialized off-heap cache we can just use the FreeableMemory size(). For
on-heap cache we can use the serializedSize * liveRatio from the CF's memtable.
> Global row cache
