title: How to create Datastore Composite Indexes with just Cloud Functions?
body: <p>I am trying to see if it's viable to just use Cloud Functions to interact with Datastore.</p>
  
  <p>Is there a way to create Composite Indexes (<em>like index.yaml</em>) with just Cloud Functions? So only Cloud Functions code, and no App Engine code.</p>
  
  <p>Thanks!</p>
