You mean process/forking API right? Honestly I'd sort of think the whole limits.py that is this rate-limiting could also be turned off by default (or a log warn message occurs) when multi-process nova-api is used since the control for that paste module actually returns the currently enforced limits (and how much remaining) and on repeated calls to different processes those values will actually be different . This adds to the confusion that this rate-limiting in-memory/process solution creates which does also seem bad.

Having something that doesn’t really work on by default now we have a threaded API is just wrong From: Rosa, Andrea (HP Cloud Services) Sent: 25 July 2013 09:35 To: OpenStack Development Mailing List Subject: Re: [openstack-dev] [Openstack-dev][nova] Disable per-user rate limiting by default I’d like to turn it off by default, as already pointed in [1] I think the rate limiting should be managed by something else (for example load balancers) in front of the API.

And on Russell's request does anyone care or prefer this to be enabled by default? Here is some more context: Earlier rate limiting discussion: http://www.gossamer-threads.com/lists/openstack/operators/28599 Related bug: https://bugs.launchpad.net/tripleo/+bug/1178529 rate limiting is per process, and doesn't act as expected in a multi-process environment: https://review.openstack.org/#/c/36516/ best, Joe Gordon
