Ive looked @ the caching mechanism for tokens in the keystone middleware. It appears that the only caching mechanism is memcache if you specify a memcache_servers. I dont see anyone has tackled https://blueprints.launchpad.net/keystone/+spec/unifed-caching-system-for-middleware . Id like to take that task on, given that we can make sure we can use more than just memcache as the cache backend. IE, configuration based. Id like to start with beaker (or any other python in memory cache if one is better), and memcache as the two first shot config based caches. Thoughts? -- Michael Basnight
