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?

A. offset: "-00:01:00" size: "00:01:00"

B. offset: "01:00:00" size: "-01:00:00"

C. offset: "01:00:00" size: "01:00:00"

D. offset: "-01:00:00" size: "01:00:00"








 

Suggested Answer: D

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"
}
]
}
}
}
