title: Can SNS route to one of multiple SQS delay queues?
body: <p>SQS has <a href="http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-delay-queues.html" rel="nofollow">delay queues</a> that can add a delay before the message is delivered.  However, they have a 120,000 cap on the total number of 'in flight' messages.  The documentation recommends falling back to another queue when a client gets an OverLimit error.  </p>
  
  <p>Is there any way to automatically fallback to another queue by the client publishing to a single SNS topic connected to several SQS delay queues?  By that, I mean that the message would generally be pushed from SNS to one of the SQS queues that has available 'in flight' capacity.</p>
