            QUESTION

            How to support multiple KeyBy in Flink
            Asked 2020-Apr-02 at 05:16

            In code sample below, I am trying to get a stream of employee records {Country, Employer, Name, Salary, Age } and dumping highest paid employee in every country. Unfortunately Multiple KEY By doesn't work.

            Only KeyBy(Employer) is reflecting, thus I don't get correct result. What am I missing?
