title: How much memory will my columnstore indexes need?
body: <p>I would like to add clustered columnstore indexes to some tables in a SQL Server 2014 database. Before doing so, I need to gather a good estimate of required memory.  How can I predict clustered columnstore memory usage?</p>
  
  <p>Things I know:</p>
  
  <ul>
  <li>The size of the tables on disk </li>
  <li>How the tables will be queried </li>
  <li>The growth rate of these tables on disk</li>
  </ul>
