| |
| 4 | CPS-E-08 | All events should use Cloud Events format | https://cloudevents.io/ |
Error Handling
# | Error Scenario | Expected behavior |
|---|---|---|
| 1 | Non responding DMIs (configurable timeout) | An error message listing the 'pending' CM Handle IDs |
| 2 | Non Existing or non-valid CM Handle Ids | An error message listing the 'rejected' CM Handle IDs |
| 3 | DMI Plugin without CM Event subscription support | An error message listing the 'rejected' CM Handle IDs |
| 4 | Late (after timeout defined in #1) responding DMIs | A message contain the (now) successful CM Handle IDs TBC No need to merge late messages from different DMIs |
Capabilities
# | Parameter | Expectation | Notes |
|---|---|---|---|
| 1 | Frequency of LCM Events | No high volume of such events is expected For testing purposed 1 LCM event per minute would suffice |
Out-of-scope
- Working with the wildcards.Subscription Delete ( which would be taken part of other story ) , only list of specific CM Handle IDs are supported
- Subscription Update scenario scenarios for an ongoing subscription.
...
- Page to keep track of the underlying use case for Subscription Create and Subscription Delete.
- The events used will adhere to CNCF Cloud Events.
- NCMP wil not be responsible for keeping the 'state' of any subscription and thus decide which CM Events should be forwarded
