Yes, in the sense that any transformation that can be expressed in the
SQL-like DataFrame API will push down to the JVM, and take advantage of
other optimizations, avoiding the data movement to/from Python and more.
But you can't do this if you're expressing operations that are not in the
DataFrame
Please see my this test:

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 Pytho

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

This would be super useful. Thanks.

At least, Spark Streaming doesn't support Python at this moment, right?

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 hea
