Ok, and if using a redelivery-delay is not an option any recommended way to manage it? My best option by now is doing a pre-processing by not enqueuing dependent messages and have a listener to enqueue them when it's dependant was processed Or checking before processing a message if there is another in which it depends, forcing the dependent message to be redelivered also,...
About what you comment regarding performance, it's not a very high-performance environment with very high throughput. It's better to be resilient and have strict order guarantee and exponential backoff retries to cover problems with external integrations. And by using message-groups it allows us to only lock messages that are on the same message-group, while allowing another messages to process normally, that is exactly the use case we want.
