Where does data preparation executes when using a Remote Engine?

[Luis_Simoes]

Hi,

I have a bunch of CSV files stored in Azure Data Lake that I want to be able to run a data preparation on...

Since all of our architecture is isolated on a private network it is mandatory to use the Remote Engine. Does this means that the data preparation will have to download the file from the Azure Data Lake to the Remote Engine server and then upload it again?

This will add so much extra network overhead.

Thank you
