      Description

      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.
