> When adding a new DC, keyspaces must be manually updated to replicate to the
> new DC. This is problematic for system_auth, as it cannot achieve LOCAL_ONE
> consistency (for a non-cassandra user), until its replication options have
> been updated on an existing node.
> Ideally, system_auth could be set to an "All Nodes strategy" that will
> replicate it to all nodes, as they join the cluster. It also removes the
> need to update the replication factor for system_auth when adding nodes to
> the cluster to keep with the recommendation of RF=number of nodes (at least
> for small clusters).
