> Auth tables should use higher consistency level
> -----------------------------------------------
>
>                 Key: CASSANDRA-8016
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8016
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: T Jake Luciani
>             Fix For: 2.1.x
>
>
> The Auth code in Cassandra uses CL.ONE or CL.LOCAL_ONE except in the case of the superuser.
> Since the Auth keyspace is created with RF=1 the default experience is fine.
> However if you change to RF > 1 suddenly the select statements are open to misses.
> We should change reads/writes in Auth, PasswordAuthenticator, CassandraAuthorizer to
always use LOCAL_QUORUM/QUORUM.
> For reads we could optimize the code to start with CL.ONE and on a miss increase to CL.QUORUM
