How should you configure the self-dependency for Trigger1?

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"

Answer: D

Explanation:

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"

}

]

}

}

}
