Thanks @findepi I think this process go through iterations, and easier than was before but still far from perfect. The ScalarUDFImpl common trait is already a huge help, but for example dynamic typing, like `MAX/MIN/GREATEST` when return type depends on input is gonna be challenging, in Trino it seems also implemented in runtime rather than static. Rust can benefit from macros and generate functions with all possible output types combinations, but this is just 1 problem. I'm totally down if we can make it easier -- This is an automated message from the Apache Git Service.
