So...it would go something like: (1) Setup

IncrementalDataSet

(2) Run logic within function. If dataset is empty, it will just return an empty

DataFrame

. (3) That

DataFrame

gets saved as a parquet within S3. (4) That parquet gets loaded within the next node. Its (4) that I'm not sure about. That would load a an empty parquet which would require some subsequent handling, I suspect.
