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 and single 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 :
Note : Avoid for wild card * (for all cm handles) |
Possible Topic Names
# | Source | Destination | Content | Topic NameDestination | |
---|---|---|---|---|---|
1 | Client Apps | NCMP | Subscription Create Event | cm-avc-subscription | NCMP |
2 | NCMP | DMI Plugins | Forwarded Subscription Create Event | ncmp-dmi-cm-avc-subscription | DMI Plugins-{DMI-DATA-SERVICE-NAME} |
3 | DMI Plugins | NCMP | Forwarded Subscription Create Event Response | dmi-ncmp-cm-avc-subscription | NCMP|
4 | NCMP | Client Apps | Subscription Create Event Outcome | cm-avc-subscription-response | Client Apps
Implementation Details
Client apps e.g. DME would publish Subscription Create Event to the topic cm-avc-subscription.

- Response in two steps
- Ack (response with DMI plugin detais e.g. DMI X and Y has started to processing)
- Process result response: 2 out of 3 DMI has responed. (The percentage is %66.)
- Response in a single step
- Process result response: 2 out of 3 DMI has responed. (The percentage is %66.)
