             Summary: Add DISTINCT operator for streaming tables that leverages time attributes
                 Key: FLINK-10488
                 URL: https://issues.apache.org/jira/browse/FLINK-10488
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
            Reporter: Fabian Hueske


We can add a special DISTINCT operator that leverages time attributes and thereby avoids materializing the complete input table.

This operator can also be used to evaluate UNION by rewriting UNION to UNION ALL + DISTINCT.
