Instances Determine Subscribers and Durables

When an application uses persistence stores and durables, application instances determine, for each endpoint, the mapping from subscriber names to static durables.

See Configuration of Durable Subscribers in an Application Instance, and Instance Matching for Subscriber Name Mapping.

Note: This mapping is not relevant when an application program supplies a durable name rather than a subscriber name.
Note: This mapping does not apply to dynamic durables, only to static durables.
