1. 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

   • 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.
    So regardless if the change is to orchestration-status or some other parameter, the AAI-EVENT is emitted. All pointers to any associated documentation, notes or code snippets appreciated.
2. 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)
