All Implemented Interfaces:
Cloneable, BeamRelNode, org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.plan.RelOptNode, org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.rel.RelNode
public class BeamMatchRel extends org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.rel.core.Match implements BeamRelNode
BeamRelNode to replace a Match node.

The BeamMatchRel is the Beam implementation of MATCH_RECOGNIZE in SQL.

For now, the underline implementation is based on java.util.regex.

      public BeamCostModel beamComputeSelfCost(org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.plan.RelOptPlanner planner, BeamRelMetadataQuery 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))

    • estimateNodeStats

      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
      invalid reference 
      org.apache.beam.sdk.extensions.sql.impl.rel.BeamSqlRelUtils#getNodeStats(org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.rel.RelNode, org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.rel.metadata.RelMetadataQuery)
