title: Firebase Cloud Function trigger
body: <p>As I know currently Cloud Functions doesn't support triggering functions from Firebase.</p>
  
  <p>For now I'm planing to use an basic Engine instance to trigger the functions based on the queue.</p>
  
  <p>Is this the right way to go? or should I trigger the cloud function directly from the clients device after the data is inserted in the db? </p>
  
  <p>thank you</p>
