Max Michels reassigned FLINK-1486: ---------------------------------- Assignee: Max Michels > Add a string to the print method to identify output > --------------------------------------------------- > > Key: FLINK-1486 > URL: https://issues.apache.org/jira/browse/FLINK-1486 > Project: Flink > Issue Type: Improvement > Components: Local Runtime > Reporter: Max Michels > Assignee: Max Michels > Priority: Minor > Labels: usability > > The output of the {{print}} method of {[DataSet}} is mainly used for debug > purposes. Currently, it is difficult to identify the output. > I would suggest to add another {{print(String str)}} method which allows the > user to supply a String to identify the output. This could be a prefix before > the actual output or a format string (which might be an overkill). > {code} > DataSet data = env.fromElements(1,2,3,4,5); > {code} > For example, {{data.print("MyDataSet: ")}} would output print > {noformat} > MyDataSet: 1 > MyDataSet: 2 > ... > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
