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 or 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.
