------------------------------------

             Summary: Unify built-in and user-defined functions in the API
                 Key: FLINK-12710
                 URL: https://issues.apache.org/jira/browse/FLINK-12710
             Project: Flink
          Issue Type: New Feature
          Components: Table SQL / API
            Reporter: Timo Walther
            Assignee: Timo Walther


Currently, there are three completely different stacks of functions: Table API builtins, SQL builtins, and user-defined types.

Currently, 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.
