title: Twemproxy key distribution
body: <p>How twemproxy uses hash function and keys distribution method to decide which key will go to which shard?
  Is there any in which lib or code i can use to specify which hash function to use and given set of servers, can it tell which shard it will go to?
  (mine uses distribution - ketama and hash - fnv1a_64 )</p>
  
  <p>Any help is appreciated</p>
