Biggest thing to watch out with this approach is that you will inevitably have some failure or bug that will 10x, 100x, or 1000x the rate of dead messages and that will overload your DLQ database. You need a circuit breaker or rate limit on it.

This! Only thing worse than your main queue backing off is you dropping items from going into the DLQ because it can’t stay up.

If you can’t deliver to the DLQ, then what? Then you’re missing messages either way. Who cares if it’s down this way or the other?
