> Add a string to the print method to identify output for DataStream
> ------------------------------------------------------------------
>
> Key: FLINK-9850
> URL: https://issues.apache.org/jira/browse/FLINK-9850
> Project: Flink
> Issue Type: New Feature
> Components: DataStream API
> Reporter: Hequn Cheng
> Assignee: vinoyang
> Priority: Major
>
> The output of the print method of {[DataSet}} allows the user to supply a
> String to identify the output(see
> [FLINK-1486|https://issues.apache.org/jira/browse/FLINK-1486]). But
> {[DataStream}} doesn't support now. It is valuable to add this feature for
> {{DataStream}}
