title: Order By any field in Cassandra
body: <p>I am researching cassandra as a possible solution for my up coming project. The more I research the more I keep hearing that it is a bad idea to sort on fields that is not setup for sorting when the table was created. </p>
  
  <p>Is it possible to sort on any field? If there is a performance impact for sorting on fields not in the cluster what is that performance impact? I need to sort around or about 2 million records in the table.</p>
