Error Handling
| # | Error Scenario | Expected behavior |
|---|---|---|
| 1 | What happens if we receive a Cm Data AVC event for replace , but there is no corresponding record in CPS-Cache ? | |
| What happens when the updating of the cache fails ? Do we still send the messages to kafka ? |
Characteristics
| # | Parameter | Expectation | Notes |
|---|---|---|---|
| 1 | Frequency of VES Message from VES Standardized device | ||
| Frequency of DMI Data AVC Event sent out from DMI plugin to NCMP |
Out-of-scope
- Any operation other than "replace" . eg : create , merge , delete etc.
Assumptions
# | Assumption | Notes |
|---|---|---|
| 1 | The model is already present in CPS and we have the data corresponding to it. | CPS is not responsible for taking care of the model. |
| 2 | "Replace" operation is only supported. | |
Issues & Decisions
# | Issue | Notes | Decision |
|---|---|---|---|
| 1 | Do we persist the incoming CM Data AVC Event in our database ? | ||
| 2 | Which model to be used for the data in the cache ? | ||
| 3 | Who will upload the model ? will it be done using our model-loader way ? | ||
| 4 | How will the data be uploaded which will later be updated ? | ||
| 5 | What happens once the data is updated ? Is cps-core responsible to send out the updated events ? | ||
| 6 | Frequency of VES message , which determines the frequency of Data AVC events. | ||
| 7 | Which datastore to be used in CPS? |
