title: Batch Mutation In Cassandra?
body: <p>I want to update multiple rows in 2 CF's.
  I don't care about the order they get updated ?
  But is it guaranteed that if one gets succeeded then eventually others will get too if some C* node fails in between ?</p>
  
  <p>Hector BatchMutation class use batch update or atomic batch update as these are two separate things.</p>
