Unify built-in and user-defined functions in the API modules

    XMLWordPrintableJSON

    Details

      Description

      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.
