Class WorkProcessorOperatorAdapter.Factory

java.lang.Object

io.trino.operator.WorkProcessorOperatorAdapter.Factory

All Implemented Interfaces:

JoinOperatorFactory, OperatorFactory

Enclosing class:

WorkProcessorOperatorAdapter

public static class WorkProcessorOperatorAdapter.Factory
extends Object
implements OperatorFactory, JoinOperatorFactory

Provides OperatorFactory implementation for WorkProcessorSourceOperator. This class implements JoinOperatorFactory interface because it's required to propagate LookupJoinOperatorFactory implementation of JoinOperatorFactory.createOuterOperatorFactory(). For non-join operators createOuterOperatorFactory() returns Optional.empty().
