      Description

      In thinking about ways to improve random-read access, a very typical access pattern for web sites is to primarily be retrieving from new records but having a much larger total dataset in a given table.

      If you could specify a Memcache flush TTL, you could keep "past 24 hours" in memory and this would give you a sliding window updated on memcache flushes. Must also adapt to regionserver memory pressure.
