Method Detail

getPipelineOptions

public java.util.Map<java.lang.String,java.lang.String> getPipelineOptions()

Description copied from interface: BeamRelNode

Perform a DFS(Depth-First-Search) to find the PipelineOptions config.

Specified by:

getPipelineOptions in interface BeamRelNode

buildPTransform

public PTransform<PCollectionList<Row>,PCollection<Row>> buildPTransform()

Specified by:

buildPTransform in interface BeamRelNode

estimateNodeStats

public NodeStats estimateNodeStats(org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.rel.metadata.RelMetadataQuery 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 BeamSqlRelUtils.getNodeStats( org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.rel.RelNode, org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.rel.metadata.RelMetadataQuery) instead.

Specified by:

estimateNodeStats in interface BeamRelNode

beamComputeSelfCost

public BeamCostModel beamComputeSelfCost(org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.plan.RelOptPlanner planner,
                                         org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.rel.metadata.RelMetadataQuery mq)

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
