In this example, when a task is transitioned to the
Resolved state, a history event is sent to the
data-history topic and tracked by a Kafka consumer.
This history event provides general information about everything related to the change in
the task status including the user and task identifications, the transaction
identification and the update details listed under detail. In order to
track specific actions, you need to filter on such information when configuring the
Kafka Java consumer.
Below is an example of the data structure in the history event about a task transitioned to Resolved state:
{
"id": null,
"timestamp": 1546524809436,
"resourceType": "org.talend.datasteward.tasks.model.Task",
"resourceId": "5c26474248f8a60001270599",
"type": "UPDATE",
"userId": "3836ef07-e6f6-4b13-9579-85afcce18328",
"transaction": "dac7ab47-687e-43df-b20f-a30ae5a13f62",
"action": "transition",
"actionParameters": {
"system_campaignId": "5c26474148f8a60001270595",
"system_state": "To validate",
"transitionName": "Accept"
},
"detail": [{
"path": "assignee",
"type": "DELETE",
"previousValue": "3836ef07-e6f6-4b13-9579-85afcce18328",
"newValue": null
}, {
"path": "completed",
"type": "UPDATE",
"previousValue": false,
"newValue": true
}, {
"path": "currentState",
"type": "UPDATE",
"previousValue": "To validate",
"newValue": "Resolved"
}, {
"path": "targetState",
"type": "DELETE",
"previousValue": "Resolved",
"newValue": null
}, {
"path": "targetTransition",
"type": "DELETE",
"previousValue": "Accept",
"newValue": null
}]
}Below is another example of the data structure in the history event when a task priority is updated:
{
"id": null,
"timestamp": 1546598273434,
"resourceType": "org.talend.datasteward.tasks.model.Task",
"resourceId": "task1",
"type": "UPDATE",
"userId": "user1",
"transaction": "91440277-ea7f-4803-9f39-c7c2969e4714",
"action": "editPriority",
"actionParameters": {
"system_campaignId": "c1",
"system_state": "Inprogress",
"priority": 3
},
"detail": [
{
"path": "priority",
"type": "UPDATE",
"previousValue": 1,
"newValue": 3
}
]
}
