> --------------------------------------------
>
> Key: FLINK-4029
> URL: https://issues.apache.org/jira/browse/FLINK-4029
> Project: Flink
> Issue Type: Improvement
> Components: DataStream API
> Reporter: Rami
> Assignee: Ivan Mushketyk
> Priority: Minor
>
> I can use keyBy as follows:
> stream.keyBy(“pojo.field1”,”pojo.field2”,…)
> Would make sense that I can use sum for example, to do its job for more than one field:
> stream.sum(“pojo.field1”,”pojo.field2”,…)
