    • getEncoding

      Description copied from interface: Prel
      A Prel's own SelectionVector mode - i.e whether it generates an SV2, SV4 or None

    • prepareForLateralUnnestPipeline

      public Prel prepareForLateralUnnestPipeline(List<org.apache.calcite.rel.RelNode> children)
      Description copied from interface: Prel
      If the operator is in Lateral/Unnest pipeline, then it generates a new operator which knows how to process the rows accordingly during execution. eg: TopNPrel -> SortPrel and LimitPrel Other operators like FilterPrel, ProjectPrel etc will add an implicit row id to the output.
