title: Using Sessions in Cassandra
body: <p>When using cassandra datastax java driver, When can I use multiple sessions under same cluster? I am not able to find any good usecase for having a cluster and multiple sessions.
  My application have multiple components/modules that accesses Cassandra. Based on the answer I may decide Should I be having one session per component/module or just one session shared across all the components of my application. </p>
  
  <p><strong>Update</strong>: Everywhere on the internet they recommend to use one session. I get it, but my question is "in what scenario do you create multiple sessions for one cluster?". If there is no such scenario, why the library allows to create multiple sessions, instead the library can just have a method to return a singleton session object.</p>
