类 BatchExecExchange

java.lang.Object

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

org.apache.flink.table.planner.plan.nodes.exec.common.CommonExecExchange

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

所有已实现的接口:

BatchExecNode<org.apache.flink.table.data.RowData>, ExecNode<org.apache.flink.table.data.RowData>, ExecNodeTranslator<org.apache.flink.table.data.RowData>, SingleTransformationTranslator<org.apache.flink.table.data.RowData>

public class BatchExecExchange
extends CommonExecExchange
implements BatchExecNode<org.apache.flink.table.data.RowData>

This ExecNode represents a change of partitioning of the input elements for batch.

TODO Remove this class once FLINK-21224 is finished.

方法详细资料

setRequiredExchangeMode

public void setRequiredExchangeMode(@Nullable
                                    org.apache.flink.streaming.api.transformations.StreamExchangeMode requiredExchangeMode)

getDescription

public String getDescription()

从接口复制的说明: ExecNode

Returns a string which describes this node.

指定者:

getDescription 在接口中 ExecNode<org.apache.flink.table.data.RowData>

覆盖:

getDescription 在类中 ExecNodeBase<org.apache.flink.table.data.RowData>

translateToPlanInternal

protected org.apache.flink.api.dag.Transformation<org.apache.flink.table.data.RowData> translateToPlanInternal(org.apache.flink.table.planner.delegation.PlannerBase planner,
                                                                                                               ExecNodeConfig config)

从类复制的说明: ExecNodeBase

Internal method, translates this node into a Flink operator.

指定者:

translateToPlanInternal 在类中 ExecNodeBase<org.apache.flink.table.data.RowData>

参数:

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.
