When subscribing data change notification with the child-nodes-only mode, the notification includes unnecessary data change events for the list key nodes in the data path.
For example, when the keepalive-delay value of a NETCONF node is updated with the following PUT request
PUT /rests/data/network-topology:network-topology/topology=topology-netconf/node=netconf-mdsal1/netconf-node-topology:keepalive-delay { "netconf-node-topology:keepalive-delay": 180 }
A notification message like this is generated:
{ "urn-ietf-params-xml-ns-netconf-notification-1.0:notification": { "event-time": "2023-09-08T18:12:43.16825253Z", "urn-opendaylight-params-xml-ns-yang-controller-md-sal-remote:data-changed-notification": { "data-change-event": [ { "path": "/urn-TBD-params-xml-ns-yang-network-topology:network-topology/urn-TBD-params-xml-ns-yang-network-topology:topology/urn-TBD-params-xml-ns-yang-network-topology:topology[urn-TBD-params-xml-ns-yang-network-topology:topology-id='topology-netconf']/urn-TBD-params-xml-ns-yang-network-topology:topology-id", "data": { "network-topology:topology-id": "topology-netconf" }, "operation": "updated" }, { "path": "/urn-TBD-params-xml-ns-yang-network-topology:network-topology/urn-TBD-params-xml-ns-yang-network-topology:topology/urn-TBD-params-xml-ns-yang-network-topology:topology[urn-TBD-params-xml-ns-yang-network-topology:topology-id='topology-netconf']/urn-TBD-params-xml-ns-yang-network-topology:node/urn-TBD-params-xml-ns-yang-network-topology:node[urn-TBD-params-xml-ns-yang-network-topology:node-id='netconf-mdsal1']/urn-opendaylight-netconf-node-topology:keepalive-delay", "data": { "netconf-node-topology:keepalive-delay": 180 }, "operation": "updated" }, { "path": "/urn-TBD-params-xml-ns-yang-network-topology:network-topology/urn-TBD-params-xml-ns-yang-network-topology:topology/urn-TBD-params-xml-ns-yang-network-topology:topology[urn-TBD-params-xml-ns-yang-network-topology:topology-id='topology-netconf']/urn-TBD-params-xml-ns-yang-network-topology:node/urn-TBD-params-xml-ns-yang-network-topology:node[urn-TBD-params-xml-ns-yang-network-topology:node-id='netconf-mdsal1']/urn-TBD-params-xml-ns-yang-network-topology:node-id", "data": { "network-topology:node-id": "netconf-mdsal1" }, "operation": "updated" } ] } } }
Note that there are data change events for topology-id & node-id, which are the key nodes of topology & node, respectively, in addition to keepalive-delay.
This is quite confusing and makes it harder to understand what has changed.
