Role of NiFi Cluster Coordinator

[#1]

with NiFi 1.0 The Cluster Coordinator is responsible for disconnecting and connecting nodes. What does that exactly mean and a use case would be appreciated. Additionally does it perform any other task?

I found the information here

https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html

NiFi Cluster Coordinator: A NiFi Cluster Cluster Coordinator is the node in a NiFI cluster that is responsible for carrying out tasks to manage which nodes are allowed in the cluster and providing the most up-to-date flow to newly joining nodes. When a DataFlow Manager manages a dataflow in a cluster, they are able to do so through the User Interface of any node in the cluster. Any change made is then replicated to all nodes in the cluster.
