public class BeamMinusRel extends org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.rel.core.Minus implements BeamRelNode
BeamRelNode
to replace a Minus
node.
Corresponds to the SQL EXCEPT
operator.

BeamRelNode
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)

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 BeamSqlRelUtils.getNodeStats(
