Vishy Kasar updated CASSANDRA-8194: ----------------------------------- Attachment: (was: auth-failure.txt) > 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 > Assignee: Vishy Kasar > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
