        public NodeStats estimateNodeStats​(BeamRelMetadataQuery mq)
        Description copied from interface: BeamRelNode
        This method is called by org.apache.beam.sdk.extensions.sql.impl.planner.RelMdNodeStats. This is currently only used in SQLTransform Path (and not JDBC path). When a RelNode wants to calculate its BeamCost or estimate its NodeStats, it may need NodeStat of its inputs. However, it should not call this directly (because maybe its inputs are not physical yet). It should call org.apache.beam.sdk.extensions.sql.impl.rel.BeamSqlRelUtils#getNodeStats( org.apache.beam.vendor.calcite.v1_40_0.org.apache.calcite.rel.RelNode, org.apache.beam.vendor.calcite.v1_40_0.org.apache.calcite.rel.metadata.RelMetadataQuery) instead.

        Description copied from interface: BeamRelNode
        This method is called by org.apache.beam.sdk.extensions.sql.impl.CalciteQueryPlanner.NonCumulativeCostImpl. This is currently only used in SQLTransform Path (and not JDBC path). This is needed when Calcite Query Planner wants to get the cost of a plan. Instead of calling this directly for a node, if we needed that it should be obtained by calling mq.getNonCumulativeCost. This way RelMetadataQuery will call this method instead of ComputeSelfCost if the handler is set correctly (see org.apache.beam.sdk.extensions.sql.impl.CalciteQueryPlanner#convertToBeamRel(String))
