--------------------------------------

             Summary: Reading from Auth table should not be in the request path
                 Key: CASSANDRA-8194
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8194
             Project: Cassandra
          Issue Type: Bug
            Reporter: Vishy Kasar
         Attachments: auth-failure.txt

We use PasswordAuthenticator and PasswordAuthorizer. The system_auth has a RF of 10 per DC over 2 DCs. The permissions_validity_in_ms is 5 minutes. 

We still have few thousand requests failing each day with the attached trace. The reason for this is read cache request realizing that cached entry has expired and doing a blocking request to refresh cache. 

We should have cache refreshed periodically only in the back ground. The user request should simply look at the cache and not try to refresh it.
