Microsoft Exam DP-203 Topic 7 Question 67 Discussion
Topic #: 7
You have an Azure Data Factory pipeline named pipeline1 that is invoked by a tumbling window trigger named Trigger1. Trigger1 has a recurrence of 60 minutes.
You need to ensure that pipeline1 will execute only if the previous execution completes successfully.
How should you configure the self-dependency for Trigger1?
Tumbling window self-dependency properties
In scenarios where the trigger shouldn't proceed to the next window until the preceding window is successfully completed, build a self-dependency. A self-dependency trigger that's dependent on the success of earlier runs of itself within the preceding hour will have the properties indicated in the following code.
Example code:
'name': 'DemoSelfDependency',
'properties': {
'runtimeState': 'Started',
'pipeline': {
'pipelineReference': {
'referenceName': 'Demo',
'type': 'PipelineReference'
}
},
'type': 'TumblingWindowTrigger',
'typeProperties': {
'frequency': 'Hour',
'interval': 1,
'startTime': '2018-10-04T00:00:00Z',
'delay': '00:01:00',
'maxConcurrency': 50,
'retryPolicy': {
'intervalInSeconds': 30
},
'dependsOn': [
{
'type': 'SelfDependencyTumblingWindowTriggerReference',
'size': '01:00:00',
'offset': '-01:00:00'
}
]
}
}
}
