Jason Brown commented on CASSANDRA-5348:
----------------------------------------

Still looking for some blood, huh :) ? I think that is a reasonable compromise, 
as we resolve some technical debt yet retain the better part of that 
implementation (the off heap part).

So, +1 to [~jbellis]'s suggestion.

> The row (partition) cache easily does more harm than good.  People expect it 
> to act like a query cache but it is very different than that, especially for 
> the wide partitions that are so common in Cassandra data models.
> Making it off-heap by default only helped a little; we still have to 
> deserialize the partition to the heap to query it.
> Ultimately we can add a better cache based on the ideas in CASSANDRA-1956 or 
> CASSANDRA-2864, but even if we don't get to that until 2.1, removing the old 
> row cache for 2.0 is a good idea.
