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))

Specified by:

beamComputeSelfCost in interface BeamRelNode

Overrides:

beamComputeSelfCost in class BeamIOSourceRel
