c'mon man this is no Brainer..Dynamic Typed Languages for Large Code Bases or
Large Scale Distributed Systems makes absolutely no sense. I can write a 10 page
essay on why that wouldn't work so great. you might be wondering why would spark
have it then? well probably because its ease of use for ML (that would be my
best guess).

In general, scala would have a much better performance than python and not all
interfaces are available in python.

That said, if you are planning to use dataframes without any UDF then the
performance hit is practically nonexistent.

Even if you need UDF, it is possible to write those in scala and wrap them for
python and still get away without the performance hit.

Python does not have interfaces for UDAFs.



I believe that if you have large structured data and do not generally need
UDF/UDAF you can certainly work in python without losing too much.

Hi Users



Thought to ask (again and again) the question: While I am building any
production application, should I use Scala or Python?



I have read many if not most articles but all seems pre-Spark 2. Anything
changed with Spark 2? Either pro-scala way or pro-python way?



I am thinking performance, feature parity and future direction, not so much in
terms of skillset or ease of use.



Or, if you think it is a moot point, please say so as well.



Any real life example, production experience, anecdotes, personal taste,
profanity all are welcome :)
