Brandon Williams updated CASSANDRA-8194:
----------------------------------------
Reviewer: Aleksey Yeschenko
> 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.
