title: Redis / Jedis: Cluster versus Pool
body: <p>I am new to Redis, Jedis and Sentinel. I am trying to educate myself using numerous web sites, code snippets and tutorials. <p>
  I have a simple understanding problem: <p>
  Some sources speak about a Redis Cluster, Jedis however uses the term Pools. 
  Are they the same thing? Or are they conceptually different?</p>
