Hi Keystone Team, We aware this deprecation information in keystone middleware. I got couple of questions. https://github.com/openstack/keystonemiddleware/blob/6e58f8620ae60eb4f26984258d15a9823345c310/releasenotes/notes/deprecate-caching-tokens-in-process-a412b0f1dea84cb9.yaml We may need to update the document for Swift. I want to clarify that if Keystone team plan to deprecate support for the EnvCache (!?) or just the in-memory non-memcache option if you don't set *neither* memcached_servers *nor* env_cache .
