srowen commented on issue #23414: [Spark 26449][PYSPARK] add a transform method to the Dataframe class URL: https://github.com/apache/spark/pull/23414#issuecomment-450660928 You can also... ``` actual_df = source_df for f in [...]: actual_df = f(actual_df) ``` Unless I'm really missing something this doesn't exist for Scala (?) and I can't see adding an API method for this. The small additional maintenance and user cognitive load just doesn't seem to buy much at all.
