- Amazon SQS provides short polling and long polling to receive messages from a queue.
| Short polling | Long Poling | |
|---|---|---|
| Default | ✅ Yes | No |
| SQS Response | Instant even if query found no messages | Wait until it collects at least 1 available message - On wait time expiry, it sends empty message. |
| Pricing | Normal | 👍 Cheaper than short poling |
