---------------------------------
Summary: Allow to set weights for controller nodes for leader
election
Key: KAFKA-18964
URL: https://issues.apache.org/jira/browse/KAFKA-18964
Project: Kafka
Issue Type: Improvement
Reporter: Luke Chen
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.
