| <div class="block">This method is called by <code>org.apache.beam.sdk.extensions.sql.impl.CalciteQueryPlanner.NonCumulativeCostImpl</code>. 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 <code>org.apache.beam.sdk.extensions.sql.impl.CalciteQueryPlanner#convertToBeamRel(String)</code>)</div> |
