public class FlinkSemiAntiJoinProjectTransposeRule extends org.apache.calcite.plan.RelOptRule
Planner rule that pushes a org.apache.calcite.rel.core.SemiJoin down in a tree past a Project.

The intention is to trigger other rules that will convert SemiJoins.

SemiJoin(LogicalProject(X), Y) → LogicalProject(SemiJoin(X, Y))
