Hi folks, I am trying to figure out an optimal flow in handling errors without losing any signals. My current flow consists of sending out an SNS to a particular lambda, and when that fails, it lands at a dedicated DLQ. I have been recommended to fanout the SNS to an SQS, to which said lambda is subscribed instead.The maximum visibility timeout is 12 hours from the time that Amazon SQS receives the ReceiveMessage request. Extending the visibility timeout does not reset the 12 hour maximum. Additionally, you may be unable to set the timeout on an individual message to the full 12 hours (e.g. 43,200 seconds) since the ReceiveMessage request initiates the timer. The configured visibility timeout is currently at the maximum of 12 hours. However, I identified the message got stuck on the consumer, and I want to return it to the queue for a retry (so it will be consumed again by another consumer). ... Serverless SQS consumer skips messages. 1.the SQS polling strategy and the visibility timeout, the Lambda dead letter configuration, function timeout and concurrency limit, as well as; the batch size of the event source mapping.
