title: Limit on number of available messages on SQS
body: <p>Based on the documentation (<a href="http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/limits-queues.html" rel="noreferrer">AWS SQS Limits</a>) the maximum number of inflight messages per queue (in a standard queue) is 120,000.<br>
  But does SQS have any limit for available messages in a queue?<br>
  I'd guess that there is no limit on the number of messages that a queue can hold in SQS, but I haven't found any explicit statement on the documentation about it.</p>
