title: Cassandra mutual exclusion locking (synchronization)
body: <p>Is there anyway to synchronise client using cassandra built in functions?</p>
  
  <p>I need to perform some operations and those operations need to be synchronized with all other clients (mutual exclusion).</p>
  
  <p>In RDBMS I can lock entire table or prepare special table for synchronization purposes and use SELECT ... FOR UPDATE on it.</p>
  
  <p>Can I achive this with Cassandra without any third party apps? If not what's the best way to do that? Preferable languages are Java and Python.</p>
