@zmb3 I've done multiple rounds of loadtesting against this change up to 10k agents, and this code path is exercised by all of our integration tests and a non-trivial subset of our unit tests. I also erred on the side of paranoia with the caching here and added a periodic forced refresh even when the replicated/event-based strategy doesn't think regen is needed, so even unforeseen issues aught to be transient in nature rather than permanently breaking. Given that, I think this is well within the "acceptable risk" threshold for a backport. |
