Class StreamExecTemporalJoin

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.stream.StreamExecTemporalJoin

All Implemented Interfaces:

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

                  producedTransformations="temporal-join",

public class StreamExecTemporalJoin
extends ExecNodeBase<org.apache.flink.table.data.RowData>
implements StreamExecNode<org.apache.flink.table.data.RowData>, SingleTransformationTranslator<org.apache.flink.table.data.RowData>

StreamExecNode for temporal table join (FOR SYSTEM_TIME AS OF) and temporal TableFunction join (LATERAL TemporalTableFunction(o.proctime)).

The legacy temporal table function join is the subset of temporal table join, the only difference is the validation, we reuse most same logic here.

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.
