Dataflows: Merge functions store data twice?

‎09-27-2023 11:42 PM

I am trying to understand how dataflows in Power BI Service store data.

If I append Table A to Table B to create Table C:
Do dataflows duplicate the data from A & B to create C and  store it twice thereby doubling the size of the data flow?

Thank you for your response.
Can you point to the exact documentation that discusses this?
I haven't found it within Microsoft's PBI site.
