Hi dear all,
I would like to share our experimental tests about, writing UDF
with Python.
So the basic idea was writing a UDF for factorial calculation.
The interesting part was to move factorial calculation logic to
Python code and then calling this Python file inside UDF code.
Here is the repo link -> UDFs-written-in-Python
The factorial calculation is here -> factorial.py
UDF code is here -> factorial.cc
Basic idea with UDF code quite simple as it has 3 parts:
1. initialization part -> factorial_init() -> all necessary
checks reside here
2. main logic -> …
