alter row transformation

Question

Hello,
In dataflow of the ADF, I am using alter row transformation before the sink which is set to use inline sinktype and Delta dataset type.
My goal is for the delta files to have delete as well as upsert.
In sink key columns I have placed all the fields which are part of the key.

Am I doing the right thing to have the correct delete and upserts?
Thank you

My settings are as follows:

Hello @arkiboys ,
Thanks for the question and using MS Q&A platform.

As we understand the ask here is howe to set the alter rows activity , please do let us know if its not accurate.
The idea is to have a condition which repords needs to be Upserted or deleted .
If you cleick on the tool tip it clarifieds the point .
"Enter an expression to match rows for insert, delete, update, or upsert. Expressions are represented in order of priority, and each row will be marked with the policy corresponding to the first-matching condition."

Just sharing an example which I have , we are setting the delete operation when the column "column_2: is null .

Please do let me if you have any queries.
Thanks
Himanshu
