             Summary: Consider removing min()/minBy()/max()/maxBy()/sum() utility methods
from the DataStream API
                 Key: FLINK-4330
                 URL: https://issues.apache.org/jira/browse/FLINK-4330
             Project: Flink
          Issue Type: Sub-task
          Components: DataStream API
            Reporter: Robert Metzger
             Fix For: 2.0.0


I think we should consider removing the min()/minBy()/max()/maxBy()/sum() utility methods
from the DataStream API. They make the maintenance of the code unnecessary complicated, and
don't add enough value for the users (who can not access the window metadata).

If we are keeping the methods, we should consolidate the min/minBy methods: the difference
is subtle, and minBy can subsume the min method.
