Long Polling decreases the number of API calls made to SQS while increasing the efficiency and latency of your application. The wait time can be between 1 sec to 20 sec (20 sec preferable) Long Polling is preferable to Short Polling Long polling can be enabled at the queue level or at th...
Long Polling (Vs Short polling or Standard polling) While the traditional SQS short polling returns immediately, even if the queue being polled is empty, SQS long polling doesn't return a response until a message arrives in the queue, or the long poll times out. What is the maximum long p...
