In DSS recipe, is it possible to add a column to a dataframe with an ID indicating the row number ?
I am using R at the moment with the command
data <- tibble::rowid_to_column(data, "ID")
but it would be great to have this function build in in DSS prepare recipe.
In a prepare recipe, you could do that with a Python formula step, provided that your data is not parallelized when processed. If your input dataset is filesystem, try checking the "Preserve ordering" option in your input dataset's Advanced settings, then adding a Python step (in "cell" mode) to your Prepare recipe, with for instance this kind of code:
count = 0
count = count + 1
You can find more info on Data ordering here.
