computeSelfCost

public org.apache.calcite.plan.RelOptCost computeSelfCost(org.apache.calcite.plan.RelOptPlanner planner,
                                                          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.Filter

copy

public KuduFilterRel copy(org.apache.calcite.plan.RelTraitSet traitSet,
                          org.apache.calcite.rel.RelNode input,
                          org.apache.calcite.rex.RexNode condition)

Specified by:

copy in class org.apache.calcite.rel.core.Filter

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

explainTerms

public org.apache.calcite.rel.RelWriter explainTerms(org.apache.calcite.rel.RelWriter pw)

Overrides:

explainTerms in class org.apache.calcite.rel.core.Filter
