-### Enabling SQS Long Polling
-
-[Long polling](http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-long-polling.html) reduces the number of empty responses by allowing Amazon SQS service to wait until a message is available in the queue before sending a response. You can enable long polling on an individual receive request by supplying the optional kwarg `:wait-time-seconds`:
-
-  :wait-time-seconds - time in seconds (bewteen 0 and 20) for SQS to wait if there are no messages in the queue. A value of 0 indicates no long polling.
-
-```clojure
-   ; ensure our queue is empty to start
-#> (get (sqs/queue-attrs client q) "ApproximateNumberOfMessages")
-"0"
-#> (let [no-polling (future (sqs/receive client q))
-         long-polling (future (sqs/receive client q :wait-time-seconds 20))]
-    (Thread/sleep 10000)                 ;; Sleep 10s before sending message
