title: More information on Columnar or 'Column-family' data model in Cosmos DB
body: <p>The documenation states that the Cosmos DB engine "<em>natively supports multiple data models: key-value, documents, graphs, and <strong>columnar</em></strong> ".</p>
  
  <p>However, I can't seem to find any other information relating specifically to the columnar model. </p>
  
  <p>There is also information available on the following APIs:</p>
  
  <ul>
  <li>DocumentDB APIs</li>
  <li>Table APIs</li>
  <li>Graph APIs</li>
  </ul>
  
  <p>But nothing on Columnar or Column-family, as described in various summaries. </p>
