Subscription Creation Events Handling
Assumptions
# | Assumption | Notes |
---|---|---|
1 | Forwarded Subscription Event |
Responses communicate asynchronously. (from DMI Plugins to NCMP) |
Then, the NCMP would wait a response(s) within the timeframe agreed on.
TBD: A single step response or two step responses will be provided in the solution.
2 | The NCMP component should create a Subscription |
Event Outcome message and publish it into the topic (cm-avc-subscription-response) |
for Client Apps consumed from |
Issues & Decisions
# | Issue | Notes | Decision | ||
---|---|---|---|---|---|
1 | Possible 'timeframe' period for timeout | DMINCMP to | NCMPClient Apps response timeout | 30 sec | (Configurable param/property). |
2 | Response in two steps or in a single step should be discussed with shareholders.(as of now) | from DMI to NCMP responses | Is the ACK would be required? No DMI-Plugin would publish actual response to NCMP | ||
3 | Response schema should be decided | from DMI to NCMP response schemas should be decided for both two steps response andsingle step response | Should DMI Plugins detail cm-hande IDs in response? Yes Accept or Decline | ||
4 | Subscription event outcome schema should be decided | from DMI to Client Apps
| We include :
