> Vectorized UDFs should technically be close to the same as normal UDFs, but 
> that is not guaranteed. For example a standard UDF might have multiple 
> overloads that the vectorized version does not.
> When users run things like 'describe function' they may not be getting the 
> correct information depending if they are in vectorized mode or not.
> [~ehans] I assigned this to you feel free to unassign it, but I think we need 
> some internal documentation for vectorized UDFs.
