But you can't do this if you're expressing operations that are not in the

Don’t use Python RDD, using dataframe instead.

I'm looking into using Python interface with Spark and came across this [1]
chart showing some performance hit when going with Python RDD. Data is ~ 7
years and for older version of Spark. Is this still the case with more recent
Spark releases?
I'm trying to understand what to expect from
Python.

Jeremy,
Did you complete this benchmark in a way that's shareable with those
interested here?

I was about to ask this question.

Hi Spark users,
I've always done all my Spark work in Scala, but occasionally people ask
about Python and its performance impact vs the same algorithm
implementation in Scala.
Has anyone done tests to measure the difference?
Anecdotally I've heard Python is a 40% slowdown but that's entirely
