alt Hacker NewsIf 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?

The point is to not take the whole server down with it. Keeps the other applications working.

Sure, but you still need to design around this problem. It’s going to be a happy accident that everything turns out fine if you don’t.
Not necessarily. If you can't deliver the message somewhere you don't ACK it, and the sender can choose what to do (retry, backoff, etc.)
Sure, it's unavailability of course, but it's not data loss.
