Issues & Decisions

#	Issue	Notes	Decision
1	Event will be forwarded under topic ncmp-dmi-cm-avc-subscription
2	Assumption is all DMIs read message and determine whether it is applicable to them based on the cmhandles included in the targets. DMIs cannot be targeted specifically as it is an async kafka message
3	Is the datastore going to be a mandatory field in the predicate body
4	In the forwarded message, cm-handle properties are added by NCMP. Is this just public properties or public and private properties
