java.lang.Object

org.apache.calcite.plan.RelOptRule

org.apache.flink.table.planner.plan.rules.logical.FlinkSemiAntiJoinJoinTransposeRule

public class FlinkSemiAntiJoinJoinTransposeRule
extends org.apache.calcite.plan.RelOptRule

Planner rule that pushes a org.apache.calcite.rel.core.SemiJoin down in a tree past a Join in order to trigger other rules that will convert SemiJoins.

• SemiJoin(LogicalJoin(X, Y), Z) → LogicalJoin(SemiJoin(X, Z), Y)
• SemiJoin(LogicalJoin(X, Y), Z) → LogicalJoin(X, SemiJoin(Y, Z))

Whether this first or second conversion is applied depends on which operands actually participate in the semi-join.
