-----------------------------------

             Summary: Count/Sum 0 elements
                 Key: FLINK-4832
                 URL: https://issues.apache.org/jira/browse/FLINK-4832
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
            Reporter: Timo Walther


Currently, the Table API is unable to count or sum up 0 elements. We should improve DataSet
aggregations for this. Maybe by union the original DataSet with a dummy record or by using
a MapPartition function. Coming up with a good design for this is also part of this issue.
