> Policy updates to different policies within a service, when successful, update the service's
policy version. If the update transactions are concurrent, and executed on different ranger-admin
servers (in HA configuration), then it is possible that policy-version of the transaction
that commits later overwrites policy-version of earlier transaction, effectively losing track
of the first change.
> If policy-version is updated after update to policy is committed, then the window of
such loss is greatly reduced.
> Similar considerations apply for tag updates.
