Constructor Detail

DrillJoinRel

public DrillJoinRel(org.apache.calcite.plan.RelOptCluster cluster,
            org.apache.calcite.plan.RelTraitSet traits,
            org.apache.calcite.rel.RelNode left,
            org.apache.calcite.rel.RelNode right,
            org.apache.calcite.rex.RexNode condition,
            org.apache.calcite.rel.core.JoinRelType joinType)

Creates a DrillJoinRel. We do not throw InvalidRelException in Logical planning phase. It's up to the post-logical planning check or physical planning to detect the unsupported join type, and throw exception.
