Class KuduSortRel

java.lang.Object
org.apache.calcite.rel.AbstractRelNode
org.apache.calcite.rel.SingleRel
org.apache.calcite.rel.core.Sort
com.twilio.kudu.sql.rel.KuduSortRel
All Implemented Interfaces:
KuduRelNode, Cloneable, org.apache.calcite.plan.RelOptNode, org.apache.calcite.rel.hint.Hintable, org.apache.calcite.rel.RelNode
public class KuduSortRel extends org.apache.calcite.rel.core.Sort implements KuduRelNode
This relation sets KuduRelNode.Implementor.sorted to true and conditionally sets KuduRelNode.Implementor.limit and KuduRelNode.Implementor.offset.

    • implement

      public void implement(KuduRelNode.Implementor implementor)
      Description copied from interface: KuduRelNode
      Each KuduRelNode implementation will accept the KuduRelNode.Implementor and manipulate it. The Implementor will then be used by the KuduToEnumerableConverter to create a Blocks that will be used to generate Byte code for the actual query.
      Specified by:
      implement in interface KuduRelNode
      Parameters:
      implementor - mutable implementator to store information on for the Kudu RPCs
