You're more or less right regarding the built in
authenticator/authorizer/role manager (which are usually referred to as
"internal" as they store their data in Cassandra tables). One important
thing to note
Jacob, seems you are on the right track however my understanding is that
only the user that was auth'd has their permissions/roles/creds cached.
Also. Cassandra will query at QUORUM for the "cassandra" user, and at
LOCAL_ONE for *all* other users. This is the same for creating users/roles.
I have similar question. when we create users or roles what is the
consistency level used?
I know, If NOT EXISTS will use SERIAL consistency. what consistency will be
used if just use CREATE USER ?
