title: S3 Notification Occurrence or SQS Reception Sequencer Ordering
body: <p>From the <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html" rel="nofollow noreferrer">Amazon S3 Event Notifications documentation</a></p>
  
  <blockquote>
    <p>In your notification configuration you can request that Amazon S3 publish events to an SQS queue. Currently, Standard SQS queue is only allowed as an Amazon S3 event notification destination, whereas FIFO SQS queue is not allowed. For more information about SQS, see Amazon SQS product detail page.</p>
  </blockquote>
  
  <p>Will the sequencer on an SQS event queue's object events reflect the order in which S3 operations occurred, or the order in which the SQS queue (non-fifo) received the events?</p>
