Interface KuduRelNode

All Superinterfaces:

Cloneable, org.apache.calcite.rel.RelNode, org.apache.calcite.plan.RelOptNode

All Known Implementing Classes:

KuduFilterRel, KuduLimitRel, KuduProjectRel, KuduProjectValuesRel, KuduQuery, KuduSortRel, KuduValuesRel, KuduWrite

public interface KuduRelNode
extends org.apache.calcite.rel.RelNode

A relational expression that represents a Kudu convention This will be used by the KuduToEnumerableConverter to translate into a Blocks. The Blocks will be used to generate Byte code that represents the query and executes it against the table. Each optimizer rule implemented in this module converts a boring basic RelNode into a KuduRelNode.

implement

void implement(KuduRelNode.Implementor implementor)

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.

Parameters:

implementor - mutable implementator to store information on for the Kudu RPCs
