Subscription identity
Use this property to specify the subscriber application identity for the subscription that is registered, deregistered, or both registered and deregistered.
In this scenario, the connector is the subscriber application that acts as a subscriber in the job. The broker manages a set of identities for each subscription. The broker uses the identities to manage subscriber requests according to their subscription attributes and duration.
If you set either Registration or Deregistration to No, the subscription identity is ignored.
Value identities are up to 128 characters. There is no default value.
