> Add support for INTERSECT
> -------------------------
>
> Key: FLINK-3942
> URL: https://issues.apache.org/jira/browse/FLINK-3942
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Affects Versions: 1.1.0
> Reporter: Fabian Hueske
> Assignee: Jark Wu
> Priority: Minor
> Fix For: 1.1.0
>
>
> Currently, the Table API and SQL do not support INTERSECT.
> INTERSECT can be executed as join on all fields.
> In order to add support for INTERSECT to the Table API and SQL we need to:
> - Implement a {{DataSetIntersect}} class that translates an INTERSECT into a
> DataSet API program using a join on all fields.
> - Implement a {{DataSetIntersectRule}} that translates a Calcite
> {{LogicalIntersect}} into a {{DataSetIntersect}}.
> - Extend the Table API (and validation phase) to provide an intersect()
> method.
