title: Cassandra as distributed cached data store
body: <p>Can we use Cassandra as a distributed in-memory cache database by utilizing its file level caching, key cache, and row cache?  </p>
  
  <p>I don't want to overload each node and I want to add more nodes to the cluster when the data grows to make this effective (to let most of my data be cached). Especially since 40% of my column families are static, and updates/insertions to other tables are not much.</p>
  
  <p>The primary aim of ours is that we need an elastic realtime data store (faster around as in memory dB) </p>
