praveentiru opened a new issue #880: URL: https://github.com/apache/arrow-datafusion/issues/880
I prefer to use Dataframe API directly and I am trying to do the same. I am new to library so, I am unable to figure out how to use certain functions in logical_plan that are declared as unary operators but actually need multiple inputs. Examples: * concat - I am assuming should take multiple columns as input and concat them * regexp_match - Physical plan refers 3 arguments, column being operated on, regex, options * split_part - This function need 3 inputs, column being split, delimiter, index of text to take Common signature in all 3 cases is: ```pub fn function_name(e: Expr) -> Expr``` Question: How does proper input expression for this to work? -- This is an automated message from the Apache Git Service.
