title: Cassandra change comparator default order
body: <p>I create the following dynamic column:</p>
  
  <pre><code>CREATE COLUMN FAMILY messages with comparator=DateType and key_validation_class=UTF8Type and default_validation_class=UTF8Type;
  </code></pre>
  
  <p>Everything is perfect,but when I list all messages</p>
  
  <pre><code>list messages;
  </code></pre>
  
  <p>or fetching it using Hector, I'm getting it in ascending order (latest date shown last). </p>
  
  <p>Is there any way to change comparator or timestamp order when creating that Column Family? </p>
  
  <p>How should I take care of situation when I need to list result in descending order (showing the latest day first)? </p>
