Stephan Ewen commented on FLINK-4330:
-------------------------------------
I the {{DataSet}} API, these methods made sense. There was also a clear
distinction between what {{max()}} and {{maxBy()}} does.
This does not work as well in the {{DataStream}} API due to some missing
features.
I think we should deprecate and remove them by the time we have a suitable
replacement via the Table API.

> 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.
