Azure 数据工厂 - 同一管道中的不同复制数据映射视图？

Question

I am trying to set up a pipeline with copy data activity in Azure Data Factory and I am confused by the different view of mapping in the copy activity. I have created the pipeline from the template "Copy data from on premise SQL Server to SQL Azure" and I am cloning the activity so there shouldn't be any differences. The source is the same in both activities and I use query against the source database.

Here's how I see it:

Original copy activity:

Cloned copy activity:

I would like to understand why I see different views of mapping.

Thanks in advance!

Answer 1

I don't that's an problem. When we clone a copy active, before we debug or run the pipeline, we need to check all the settings manually.

From your screenshots, original copy activity miss the source schema during mapping. Just import schema will be solved it.

And the cloned copy active seams import schema automatically. Not sure if all the columns are mapped(I think not). Some suggestions:

1. Please import the schema in source dataset firstly, and fully set one copy active.
2. Then clone the copy active which may avoid the problem.

Data Factory may not very smartly and even we clone active, we still should check all the settings in each actives.

Update:

Like @JeffRamos said, sinks are different then the mapping will be different.

We are glad to hear that you have figured it out:

• "I have figured it out - I was using the query that contained the "count(*)" aggregate. Removing it and the "group by" clause made the mapping view the same as for the original Copy activity."

Thanks for @JeffRamos's useful comment again.

HTH.
