Hello John, For reference, one of the environments I'm maintaining currently uses around 3.5k active destinations. The broker cluster is running on relatively modest servers without any issues. I will say though that at this point there has been some noticeable slowdowns in precisely the areas that Justin mentioned... that being said the clients (running on separate servers) report an average publish latency of ~0.8ms on the actual queues. That's quite impressive I think.

Please use caution responding, opening attachments or clicking embedded links. *** There is certainly a practical limit, but I doubt anybody has a clear view of what it is. I think you're more likely to hit pain points with management (e.g. the web console) before the queues themselves cause problems.

We tend to keep them around for a while (like an hour) to service job status after the job is complete, but this can result in a lot of mostly-idle queues. Is there a practical limit at which Artemis becomes unhappy (low memory, sluggish performance)? I'm sure it depends on VM sizing, but let's just say that we have Artemis running in a K8S pod with 4GB memory available and 4vcpus. I'm only looking for an order-of-magnitude ballpark. Something like "no more than N per GB memory" would be great.
