The acknowledgment-sending portion of the client-side aspect stack is "unaware" that it just went through a failover and it will dully continue to behave as designed, i.e. sending acknowledgments for messages being consumed. It's the secondary server job to realize that the acknowledgments arriving for deliveries it actually does not have (or better said, did not create by actually sending messages) are legit, and are generated by "salvaged" non-persistent messages.

That's a poor solution.

So you're going to send unnecessary traffic across the network, plus add fiddly code on the server side to create deliveries for non existent non persistent messages just to avoid changing a few lines of code on the client side?
