Tsz-wo Sze commented on RATIS-967:
----------------------------------
We may add "preferred leader" to SetConfigurationRequest as a part of the
configuration so that the request will become a transaction replicated to all
the servers. Then, all the servers know who is the preferred leader P. They
will yield the leadership to P unless P is dead.
BTW, we may consider adding "leader priority" instead of "preferred leader" to
each server. Lower priority servers yield to higher priority servers.
