> In the stretch cluster environment, the nodes are located in different data
> center for disaster recovery. So the backup cluster controller nodes should
> be served as the follower. Only when the disaster happened, the controller
> nodes in backup cluster need to be elected as leader. In our current design,
> the candidate node is randomly chosen. We can consider to apply the "weight"
> to the controller nodes to achieve the situation mentioned above.
