I have set the Maximum Receives to 1 as that is the minimum and the visibility timeout on my trigger queue to 5 minutes. After the successful processing, you delete the message from the queue. It can be that a consumer receives a message more than once (this is by design, and you should handle that in your logic). When the ReceiveCount value exceeds the maxReceiveCount value for a queue, Amazon SQS moves the message to the DLQ. The SQS queue has a DLQ with a max receive count of 2.
