Class PartitionOperator<T>

java.lang.Object

org.apache.flink.api.java.DataSet<OUT>

org.apache.flink.api.java.operators.Operator<OUT,O>

org.apache.flink.api.java.operators.SingleInputOperator<T,T,PartitionOperator<T>>

org.apache.flink.api.java.operators.PartitionOperator<T>

Type Parameters:

T - The type of the data being partitioned.

@Deprecated
@Public
public class PartitionOperator<T>
extends SingleInputOperator<T,T,PartitionOperator<T>>

Deprecated.

All Flink DataSet APIs are deprecated since Flink 1.18 and will be removed in a future Flink major version. You can still build your application in DataSet, but you should move to either the DataStream and/or Table API.

This operator represents a partitioning.
