[GitHub] flink issue #2265: [FLINK-3097] [table] Add support for custom functions in ...

Github user wuchong commented on the issue:

    Do we have any google docs or FLIP talking about this design ? 
    
    I think the `ScalarFunction` has too many internal functions, and should not be exposed to users. Maybe we can create a new interface for custom functions, such as `UDF` or `UserDefinedFunction`.
