---------------------------------
Summary: Distinct operator for POJO DataSets without KeySelector
and on UnsortedGrouping
Key: FLINK-984
URL: https://issues.apache.org/jira/browse/FLINK-984
Project: Flink
Issue Type: Improvement
Reporter: Ufuk Celebi
Priority: Minor
Two issues regarding the distinct operator:
- The distinct operator does not support {{distinct()}} with POJO datasets. I
think it should be possible to implement a reflection based KeySelector which
selects all public fields as key?
- All other grouped operators work by {{groupBy(GROUPING).operator(...)}}
whereas the distinct operator does {{distinct(GROUPING)}}. I think it would be
more consistent to allow {{groupBy(GROUPING).distinct()}}.
