Subscription Create Response Handling Dmi Part
- Consume suscription event (payload) with kafka message key and kafka timestamp from ncmp, and extract cm handle ids. - Generate subscription event response (payload) and revert it back to ncmp to specified topic with the corresponding kafka message key. - Configure kafka consumer properties and dmi service name.
