The POJO-related parts are already implemented in the current master. Do
you think the compiler tests in this pull request are relevant? I've started
porting them to our current master but got some failing tests.
> 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
> Assignee: Robert Metzger
> 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()}}.
