             Summary: Allow sorting on aggregated streaming dataframe when the output mode is Complete
                 Key: SPARK-15812
                 URL: https://issues.apache.org/jira/browse/SPARK-15812
             Project: Spark
          Issue Type: Sub-task
            Reporter: Tathagata Das
            Assignee: Tathagata Das


When the output mode is complete, then the output of a streaming aggregation essentially will contain the complete aggregates every time. So this is not different from a batch dataset within an incremental execution. Other non-streaming operations should be supported on this dataset. In this JIRA, we are just adding support for sorting, as it is a common useful functionality. Support for other operations will come later.
