U-SQL, R, Data Lake Store: Output directly from R

    Question

  • Hi,

    I'm running U-SQL script with R, reading data from Data lake store and producing some output. My problem is that the output from R is dynamic, it can have different number/names of columns. So far I understood that R output schema needs to be always defined in U-SQL so it can't be dynamic.

    I was thinking that possible workaround would be to directly store the actual result to Data Lake from R, and just produce some static dummy output for U-SQL. I can use DEPLOY to include files for read but is it possible to write directly to data lake?

    Thanks
