title: Is it possible to use Cassandra as a LRU cache
body: <p>I would like to store key-value pair in Cassandra and have entry Automatically deleted in LRU fashion when a fixed storage size is reached.</p>
  
  <p>Is it possible to do this using Cassandra, if so what would be the best way to do it.
  If not is there any other distributed storage system that would support this use-case while not having to keep all data in memory.</p>
