Code Proposal

In AAI, when the "orchestration-status", "service-instance-location-id", "input-params" for a Service Instance changes, notify ExtAPI so it does not need to poll AAI

AAI does have precedent for publishing events to DMaaP
ExtAPI to be updated to consume events from DMaaP
need to get agreement about topic configuration
Discuss with Adrian OSullivan and Ludovic Robert, to confirm whether existing AAI-EVENT topic in DMaaP suffices for this requirement
From Jimmy Forsyth (AT&T) to Everyone: 01:51 AM
@Brian, yes, AAI sends notification on all changes to DMaaP to the AAI_EVENT (or maybe it’s AAI-EVENT) topic
AAI-1996 - Getting issue details... STATUS
EXTAPI-98 - Getting issue details... STATUS
James Forsyth Can you please send us the details on what the format of the events are that are sent to DMaaP are from A&AI. For example is there only one topic called AAI-EVENT topic and any change on a service-instance is emitted to DMaaP.

In the case you are interested in, the service-instance can be CREATED, UPDATED, or DELETED (which you find in “action” in the event-header) either as a standalone object or as part of a nested structure. You can use the top-entity-type to tell you which is the containing object, and then use that to determine if a service-instance might be impacted by the operation. In the case of a service-instance update, the top-entity-type will be either customer, service-subscription, or service-instance.

For a customer or service-subscription, you would then look for a service-instance child object - in the example above, the service-instance would be in the position of the p-interface on a service-subscription and in the position of sriov-pf on a customer. All of that depends on how the client uses the interface, and AAI has no control over it. Since users can perform the operation at any of the 3 levels (with a DELETE object, sometimes there are rules about cascading deletes, I’d have to figure out of the customer/service-subscription/service-instance object hierarchy is subject to any of those rules (like it might not let you delete the service-subscription until all the service-instances are gone first; I just don’t recall the rules off the top of my head).

Regarding the "input-parameters", it was added for CCVPN use case (originally as "customer-requests") and there is an example in the comments of: AAI-CCVPN Schema Proposal for Casablanca Release For convenience, the comment is copied below:

In client code using AAI API, make use of "nodes query" as shown in newly published documentation to optimise some queries on AAI data:
- https://docs.onap.org/en/latest/submodules/aai/aai-common.git/docs/AAI%20REST%20API%20Documentation/nodesQuery.html
- Ludovic Robert For example instead of
  - "GET /aai/v11/customers/{customerId}service-subscription/{service_subscriptionId}service-instance API/{service-instanceId}"
  - use "GET /aai/v11/nodes/service-instances/service-instance/{service-instanceId}" instead
  - From Jimmy Forsyth (AT&T) to Everyone: 01:51 AM
    @Adrian the answers are yes, service-instance-id is unique in ONAP and you can query it directly with the nodes query (see link above)
