Method Details

translateToPlanInternal

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

Description copied from class: ExecNodeBase

Internal method, translates this node into a Flink operator.

Specified by:

translateToPlanInternal in class ExecNodeBase<org.apache.flink.table.data.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.

canBeTransformedToAdaptiveJoin

public boolean canBeTransformedToAdaptiveJoin()

Description copied from interface: AdaptiveJoinExecNode

Check whether the join node can be transformed to BatchExecAdaptiveJoin.

Specified by:

canBeTransformedToAdaptiveJoin in interface AdaptiveJoinExecNode

toAdaptiveJoinNode

public BatchExecAdaptiveJoin toAdaptiveJoinNode()

Description copied from interface: AdaptiveJoinExecNode

Transform this node to BatchExecAdaptiveJoin.

Specified by:

toAdaptiveJoinNode in interface AdaptiveJoinExecNode
