Vijay commented on CASSANDRA-5357:
----------------------------------
Hi Jonathan, The plan is to make the Entry<k,v> offheap (with FM in the heap)
of the map of heap after promoting the query filter.
I might end up removing the CLHM and implement a Concurrent HM to reduce the
over head...
Let me know if it is fine.

> I think that most people expect the row cache to act like a query cache,
> because that's a reasonable model. Caching the entire partition is, in
> retrospect, not really reasonable, so it's not surprising that it catches
> people off guard, especially given the confusion we've inflicted on ourselves
> as to what a "row" constitutes.
> I propose replacing it with a true query cache.
