UDF or not UDF
What happens when using the same acronym for two different features in the same product?
Find the right UDF. DAX User Defined Functions (UDFs) are the functions available in semantic models that can be defined using DAX expressions. Fabric User Data Functions (UDFs again!!) are not tied to the semantic model and are written in Python. Thus, when you just say “UDFs,” you are necessarily ambiguous.
The comic celebrates this classic Microsoft inability to name its products properly.
