It turns out in almost 100% of these cases caching was not enabled, not considered, not built into the deployment, etc.\n\nKeystone would like to be opinionated and say \"caching is required\", full stop. Rather than continuing to field questions about why token issuance or validation is tanking in performance.\n\nIf we can assume the existence of a oslo.cache compatible cache, we are able to make keystone, outside of testing, require that cache to be configured and ensure the assumptions we have made in developing keystone are more in line with real deployments (going forward) because cache is considered a base service.","commit_id":"9f2a038c129d447132c325587572bb16af30b00f"}]}
