    Description

      Seems like when these thresholds are reached we are trying to reduce the keycache and Memtable sizes, but in the trunk memtable is moved off-heap hence reducing that will not actually help.
      Reducing the keycache might help but we might want to provide a way to bring the cache level back to the configured value when the pressure goes away.

      Conversation from IRC: we might want to remove these setting all together after global keycache.
