A path service is a persistent map that can be used to store the mapping of a group of messages to a messaging resource, such as a member of a distributed destination or a store-and-forward agent. It provides a way to enforce message ordering by pinning messages to a member of a cluster hosting servlets, distributed queue members, or store-and-forward agents.
The default persistent file store requires no additional configuration. A best practice to use a custom store instead of a default store.
Note: When targeting a cluster, you must specify a custom store with the same target, a migration policy of Always, and a distribution policy of Singleton.
