title: Azure Event Trigger fires multiple times same file
body: <p>I have a blob storage container where I have configured a Event-grid trigger (Blob Created). I am loading this blob storage files through Data factory and many times it will happen that many files may come up in this blob in one shot. May be we can take an example of 20 files.</p>
  <p>The good news is my event-grid trigger is firing and the function app is called. However , I can see that sometimes for the same file the event-grid trigger is fired more than once.</p>
  <p>Out of these 20 files there are few files which are very large say 300 MB but others are pretty small like in 3KBs. So my doubt is while this 300 MB is fired and it is still processing , parallelly it picks the same 300 MB file again (since it feels that it is still not read) and is saved in db multiple times which is not want I want.</p>
  <p>Is Azure Event-grid would be the right approach for this scenario ?</p>
