Class KuduPhysType

java.lang.Object

com.twilio.kudu.sql.KuduPhysType

All Implemented Interfaces:

org.apache.calcite.adapter.enumerable.PhysType

public final class KuduPhysType
extends Object
implements org.apache.calcite.adapter.enumerable.PhysType

A partially implemented implementation of PhysType. This class produces Expressions that take as input a RowResult and fetch various fields out of it. Primarily used to construct Function1 and Predicate1 that can be used filter and project the kudu rpc result.
