title: Cassandra truncate performance
body: <p>I have been recently told that, cassandra truncate is not performant and it is anti pattern. But, I do not know why? </p>
  
  <p>So, I have 2 questions:</p>
  
  <ul>
  <li><p>Is it more performant to have upsert of all records then doing truncate?</p></li>
  <li><p>Does truncate operation creates tombstones? </p></li>
  </ul>
