                                                          org.apache.calcite.rel.metadata.RelMetadataQuery mq)

Specified by:

computeSelfCost in interface org.apache.calcite.rel.RelNode

Overrides:

computeSelfCost in class org.apache.calcite.rel.core.Project

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
