title: Is it good practice to have multiple keyspaces in Cassandra?
body: <p>I've Cassandra configured on <strong>Amazon EC2</strong> having <strong>3 nodes(instances)</strong> in <strong>single cluster</strong>. Now what I want to do is give some space on Cassandra to my clients by creating separate <strong>keyspace</strong> for each in a <strong>single cluster</strong>. Number of clients will increase day by day so there is no fix number of keyspaces I can assume to be created. </p>
  
  <p>Will there be a performance issue if I create too many keyspaces in single cluster?</p>
  
  <p>If it's not good practice, then Is there any other workaround to fit my need? I don't want to configure multiple instances of Cassandra.</p>
