Class BatchExecExecutionOrderEnforcer

java.lang.Object

org.apache.flink.table.planner.plan.nodes.exec.ExecNodeBase<RowData>

org.apache.flink.table.planner.plan.nodes.exec.batch.BatchExecExecutionOrderEnforcer

All Implemented Interfaces:

BatchExecNode<RowData>, ExecNode<RowData>, ExecNodeTranslator<RowData>, FusionCodegenExecNode

public class BatchExecExecutionOrderEnforcer
extends ExecNodeBase<RowData>
implements BatchExecNode<RowData>

Batch ExecNode for ExecutionOrderEnforcer.

ExecutionOrderEnforcer has two inputs, one of which is a source, and the other is the dependent upstream. It enforces that the input source is executed after the dependent input is finished. Everything passed from the inputs is forwarded to the output, though typically the dependent input should not send anything.

The ExecutionOrderEnforcer should generally be chained with the source. If chaining is explicitly disabled, the enforcer can not work as expected.

The operator is used only for dynamic filtering at present.

Method Detail

supportFusionCodegen

public boolean supportFusionCodegen()

Description copied from interface: FusionCodegenExecNode

Whether this ExecNode supports OFCG or not.

Specified by:

supportFusionCodegen in interface FusionCodegenExecNode

Overrides:

supportFusionCodegen in class ExecNodeBase<RowData>

translateToFusionCodegenSpecInternal

protected OpFusionCodegenSpecGenerator translateToFusionCodegenSpecInternal(org.apache.flink.table.planner.delegation.PlannerBase planner,
                                                                            ExecNodeConfig config,

Description copied from class: ExecNodeBase

Internal method, translates this node into a operator codegen spec generator.

Overrides:

translateToFusionCodegenSpecInternal in class ExecNodeBase<RowData>

Parameters:

planner - The planner.

config - per-ExecNode configuration that contains the merged configuration from various layers which all the nodes implementing this method should use, instead of retrieving configuration from the planner. For more details check ExecNodeConfig.

                                                          ExecNodeConfig config)

Description copied from class: ExecNodeBase

Internal method, translates this node into a Flink operator.

Specified by:

translateToPlanInternal in class ExecNodeBase<RowData>

Parameters:

planner - The planner.

config - per-ExecNode configuration that contains the merged configuration from various layers which all the nodes implementing this method should use, instead of retrieving configuration from the planner. For more details check ExecNodeConfig.
