Assumptions

#	Assumption	Notes
1	All information included in the subscription event will be forwarded
2	org.onap.ncmp:cm-avc-subscription-event.response will be received from the DMI as per CPS-1065 Spike: CM data notifications from NCMP to applications including subscriptions#SubscriptionSteps

Events

Forward Subscription Event

At the moment, it is up to the DMI Plugins to accept or reject
NCMP has to reject if cached dataspace is used (Cached is currently not supported)

Subscription Event Responses

NCMP will be aware of the registered DMIs and the CMHandles registered to a given DMI
1. Therefore will know how many DMIs to be waiting for a response from
2. Wait for timeout before sending event outcome? (30s)

Subscription Event Outcome

NCMP is to collate Event Responses from DMI and send.
Wait for timeout,
1. if all DMIs returned send full Event Outcome
2. else partial event outcomes

Issues & Decisions

#	Issue	Notes	Decision
1	Is the forwarding being done via an endpoint or an asynchronous kafka message	Doing via endpoint will make it complicated to forward to multiple DMIs New endpoint will have to be implemented on DMI Propose org.onap.ncmp:cm-avc-subscription-event.forward
2	Extra data needed for forwarded message? What is the schema	ID? timestamp?
