projectRowType - Fields and types to project; null to project raw row

Method Detail

copy

public org.apache.calcite.rel.RelNode copy(org.apache.calcite.plan.RelTraitSet traitSet,
                                           List<org.apache.calcite.rel.RelNode> inputs)

Specified by:

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

Overrides:

copy in class org.apache.calcite.rel.AbstractRelNode

deriveRowType

public org.apache.calcite.rel.type.RelDataType deriveRowType()

Overrides:

deriveRowType in class org.apache.calcite.rel.core.TableScan

register

public void register(org.apache.calcite.plan.RelOptPlanner planner)

Specified by:

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

Overrides:

register in class org.apache.calcite.rel.AbstractRelNode

implement

public void implement(KuduRelNode.Implementor impl)

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:

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