title: ElasticSearch: Atomic bulk update
body: <p>Is it possible to do bulk atomic updates in ElasticSearch?</p>
  
  <p>I am aware that regular bulk updates are not atomic as noted here:
  <a href="https://www.elastic.co/guide/en/elasticsearch/guide/current/bulk.html#bulk" rel="nofollow noreferrer">https://www.elastic.co/guide/en/elasticsearch/guide/current/bulk.html#bulk</a></p>
  
  <p>Is there any other way to atomically update multiple documents? i.e. Either all the updates happen or none of them do.</p>
