title: Auto scale up/down Cosmos DB RU's
body: <p>We experience throttling (429) due to burst of high traffic for a period of time. To mitigate this issue, we currently increase the RU in azure portal, and decrease it later.</p>
  
  <p>I want to scale Up/Down based on the metrics, but, it does not expose the # of physical partitions created for the document DB container.</p>
  
  <ul>
  <li>How can I get the # of physical partitions for a document DB container?</li>
  <li>If someone in this group has solved auto scaling problem, I’m eager to know how?</li>
  </ul>
