Hi Fabian, Yes, I agree 1-part/no-override is the least favorable thus I didn't include that as a voting option, and the discussion is mainly between 1-part/override builtin and 3-part/not override builtin.
Re > However, it means that temp functions are differently treated than other db objects. IMO, the treatment difference results from the fact that functions are a bit different from other objects - Flink don't have any other built-in objects (tables, views) except functions. Cheers, Bowen
