Hey Dave, In the 'default' branch only Python 2.7 UDFs are supported, Python 3 UDFs are currently in the works so you can choose which version you want to use. If you want to use Python 3 UDFs right now you can use the 'python3udf' branch instead.

Excellent! Is there a preferred/required version of Python? I was looking at the config log and I see it checking for Python2 & Python3. -----Original Message----- From: Anderson, David B [ICG-MKTS] Sent: Thursday, June 16, 2016 11:34 AM To: users-list Subject: RE: R UDFs Mark, Thanks for the info. To confirm, If I write my UDFs in Python, they will be executed in parallel (if required)?

When an R function is called a lock is acquired that prevents other R functions from running at the same time. There has been some work to running multiple interpreters in parallel in separate processes for Python UDFs, but this has not been ported to R UDFs yet.

Is there a single shared interpreter or are there multiple copies running?
