Yes. Turnstile uses Redis to coordinate rate limit configuration and bucket data, in order to provide rate limiting. > Also, I don't think this is part of the Openstack trunk code, and if > so, is there any reason why it's not part of Nova, as it was meant to > be a replacement? I wrote Turnstile to be general; it can be used for Nova, Keystone, or any other system for which rate limiting is desired. (I in fact designed it with a goal of being able to use it for some personal projects which are not OpenStack-related.) This is the primary reason it's not a direct part of any OpenStack repository. That said, it is hosted on github and I welcome pull-requests…and I'm not at all adverse to the suggestion that it become an OpenStack project; I'm just not convinced that that would be generally desired, or that it would be generally beneficial… -- Kevin L.
