If this is already explained clearly in the issue then this section is not needed. Explaining clearly why changes are proposed helps reviewers understand your changes and offer better suggestions for fixes. Please explain the problem you are trying to solve in terms of the user-visible behavior, rather than the implementation. For example, "The code in `foo.rs` doesn't handle nulls" is a symptom of the implementation. "COUNT(DISTINCT) returns wrong results when the column contains nulls" is the user-visible problem. --> Set some guidelines for how UDFs should be implemented in `datafusion-spark`. This is to align us on what we expect from UDFs, making it easier for contributors & reviewers alike. -- This is an automated message from the Apache Git Service.
