cluster

A cluster is composed of a set of Oracle Endeca Server nodes each of which can serve query requests. Only one node is identified as the leader node; All other nodes are follower nodes. There is one copy of the Oracle Endeca Server index that is shared and used by all Oracle Endeca Server nodes. Nodes can be added or removed dynamically, without having to stop the cluster.

The Cluster Coordinator provides communication between the nodes in the cluster and notifies the nodes about index updates and updates to the configuration.
