title: CosmosDB Change Feed Scaling
body: <p>I have my Azure function with CosmosDB trigger, that listens to a collection using lease collection mechanism. This function is hosted on consumption plan.</p>
  
  <p>I have noticed that under heavy load I tend to get updates to my function with a greater and greater delay. After reading documentation I did not find a way how to improve scaling of my setup. Is there a way to?</p>
