Subject [jira] Commented: (CASSANDRA-1253) Forcing CL on a per user basis

Viktor Jevdokimov commented on CASSANDRA-1253:
----------------------------------------------

Isn't it a client-side feature/rule? I don't agree that this issue is a major priority, since
it can be solved on a client side.

> The user that writes data is allowed to chose the CL they want. This presents several
challenges for administration. For example, if I am sure ALL of our applications are writing/reading
and CL.QUORUM or CL.ALL, I have some flexibility such as joining a node without auto-bootstrap.
Also a policy might be made "all data must be written at QUORUM".
> The new feature is to associate users with a list of available CL. Thus an administrator
can enable disable levels.
> {noformat}
> admin: read level [ CL.ZERO,CL.ONE,CL.QUORUM, CL.ALL ]
> user1: read level [CL.QUORUM, CL.ALL]
> {noformat}
> If the user attempts to write/read with a disallowed level an Exception can be thrown
or the request could be silently modified/upgraded to a different CL.
