Max Michels created FLINK-1486: ---------------------------------- Summary: 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 Priority: Minor
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)
