Cluster persistence and caching are configured in the cluster configuration file.
Enable persistence for clusters to maintain application and workspace settings across starts and stops of the nodes in a cluster. When you enable persistence, you can modify the directory in which the cluster configuration settings are persisted. All nodes in a cluster must point to the same persistence directory.
The cluster cache is an in-memory distributed cache used for internal sharing of cluster state and configuration. Manager nodes are members of the cache, while controller nodes are clients of the cache. Cache properties must be configured for all nodes, but you do not need to provide port information for controller-only nodes.
