Gyula Fora created FLINK-1175:
---------------------------------

             Summary: Add support for KeySelector and possibility to select more than one field for groupBy for streaming
                 Key: FLINK-1175
                 URL: https://issues.apache.org/jira/browse/FLINK-1175
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
            Reporter: Gyula Fora
            Priority: Minor


The streaming API currently only supports grouping by one field in the tuple. To match the functionality of the batch API it is necessary to add support for the KeySelector and also the possibility to select more than one field to group by.
