title: Multiple consumers of Cosmos DB Change Feed
body: <p>I'm using Change Feed Processor library (or Azure Functions Cosmos DB trigger) to subscribe to collection updates. How do I set up multiple independent (non-competing) consumers to the feed of the same collection?</p>
  
  <p>One way is to use multiple lease collections, e.g. <code>leases1</code>, <code>leases2</code> etc. But that is a bit wasteful.</p>
  
  <p>Is there a way to do that with just one lease collection? (e.g. by specifying a consumer group name somewhere, similar to Event Hubs Processor)</p>
