> In my experience in disabling the query cache in the controllers reduces the overall
memory footprint and causes very little difference in performance.  The shards will continue
to cache queries which is where the cache has the most use.  So I believe we need to remove
the cache in the controllers all together, because if a few queries the return large results
get cached in the controller, they can run out of memory.
