While it won't solve all cases, I think there is a special case here where we can add `ScalarUDFImpl::simplify` implementation to `coalesce` which would discard all trailing arguments after the first non-nullable argument. (Even better, if the first argument is non-nullable then the coalesce could be completely optimized away?) -- This is an automated message from the Apache Git Service.
