Determine source of message in DLQ
0
We are looking at ways of unifying our DLQ handling but a problem we are facing an issue with identification of the actual source. Our current approach is to have a unique DLQ for each lambda or similar (could be sns, scheduler, etc.) and then have a lambda with the DLQ as source which further processes the failed messages (could be automatic retries, storing in Dynamo for manual handling, etc.). But we think this becomes a bit cumbersome since we will quickly incur quite high fees for the polling (we have a lot of places where we need DLQs).
Our absolute dream scenario is if we could set a tag where we add the DLQ but this isn't available. An alternative would be to use the SenderID in the SQS message to identify the source but this doesn't really seem possible.
