Architectural Improvements for SNS-SQS-Lambda Integration with Symfony Messenger

Ok I got it thanks for your explanation !

It looks like we've chosen 2 totally different solutions, so I'm still very curious about what others achieve ;)

Currently, each message handler is linked to a specific transport

I'm very curious to know how you came up with this solution.

I'm very curious to know how you came up with this solution.

I spend a lot of time in finding out how I can implement a event driven architecture with SNS in combination with SQS. After a couple of tries I came to this solution. It was helpful to have specific queues for specific handlers, to handle dead letter queue entries one-by-one and not to retry already handled messages. Imagine the case that you have an event which has 2 handlers and one of them failed. This event goes to the daed-letter queue. Once I'm retrying this event, it will try to handle it with both handlers again. Just in case you have a specific question, just let me know. :)
