Issues & Decisions

#IssueNotes Decision
1Is the forwarding being done via an endpoint or an asynchronous kafka message
  1. Doing via endpoint will make it complicated to forward to multiple DMIs
  2. New endpoint will have to be implemented on DMI
  3. Propose org.onap.ncmp:cm-avc-subscription-event.forward


2Extra data needed for forwarded message? What is the schema
        1. ID?
        2. timestamp?
