> Currently, there are three completely different stacks of functions: Table API builtins, SQL builtins, and user-defined types.
> Both the Blink and the legacy planner define a separate list of functions and implementations with different type system and type checking logic.
> The long-term goal of this issue is to unify all 6 different stacks into a common one. This includes better support for type inference which relates to FLINK-12251.
