如何将 Tumbling Window 参数传递给数据工厂 UI 中的数据工厂管道？

Question

I have defined a pipeline in Azure Data Factory with a Tumbling Window trigger, as seen below:

I would like for my activities to receive the Tumbling window parameters ( trigger().outputs.windowStartTime and trigger().outputs.windowEndTime ) however I did not find any examples in the documentation showing how to do this in the UI.

Question

How can I pass the Tumbling Window parameters to a Data Factory pipeline in the Data Factory UI?

Answer 1

Assuming the pipeline that you're triggering is already paramaterised then you're nearly there.

When adding the trigger you'll see a second screen to pass parameters from the trigger.

You can then add your functions prefixed with @. So:

@trigger().outputs.windowStartTime
@trigger().outputs.windowEndTime

If you need to call a function on the parameter before you pass it you can do that too

@addHours(trigger().outputs.windowEndTime,1)

Answer 2

This answer is out of date. Parameters can be added directly in the UI - see my answer above.

Note: You cannot pass the Tumbling Windows parameters to a Data Factory pipeline in the ADF UI.

You need to pass the tumbling window parameters by following steps:

First create a Tumbling window trigger as per your requirement.

On the bottom left corner, you will find the " Triggers " tab => Click on Triggers and select the created trigger and click on " Code " and replace the parameters.

To use the WindowStart and WindowEnd system variable values in the pipeline definition, use your "MyWindowStart" and "MyWindowEnd" parameters, accordingly.

For more details, refer " MSDN " thread, which addressing similar issue.

Hope this helps.

This is because you set @trigger().outputs.windowStartTime and @trigger().outputs.windowEndTime in the variable. In fact, you should set them in the parameter, like this:
