> In a federated environment, local impairments of one sub-cluster might unfairly affect
users/queues that are mapped to that sub-cluster. A centralized component (GPG) runs out-of-band
and edits the policies governing how users/queues are allocated to sub-clusters. This allows
us to enforce global invariants (by dynamically updating locally-enforced invariants).
