Correct answer - "decrease VisibilityTimeout": The default visibility timeout for a message is 30 seconds. The minimum is 0 seconds. The maximum is 12 hours.

By setting an appropriate visibility timeout for the specific message, we can control how sooner or later the message is available for processing by other consumers. Read more:

Incorrect:

"disable LongPolling" - Long polling is a feature used to reduce the number of API calls being made to SQS.

"Use a FIFO queue" - Good for situations where duplicates should not be introduced into the queue

"Use a lower DelaySeconds" - Message is hidden when it is first added to queue, whereas for visibility timeouts a message is hidden only after it is consumed from the queue.
