Description
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.
