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

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

Type Parameters:

T - The type of the DataSet with locally sorted partitions.

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.

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

This operator represents a DataSet with locally sorted partitions.

Method Detail

useKeySelector

public boolean useKeySelector()

Deprecated.

Returns whether using key selector or not.

sortPartition

public SortPartitionOperator<T> sortPartition(int field,
                                              Order order)

Deprecated.

Appends an additional sort order with the specified field in the specified order to the local partition sorting of the DataSet.

Overrides:

sortPartition in class DataSet<T>

Parameters:

field - The field index of the additional sort order of the local partition sorting.

order - The order of the additional sort order of the local partition sorting.

Returns:

The DataSet with sorted local partitions.

sortPartition

public SortPartitionOperator<T> sortPartition(String field,
                                              Order order)

Deprecated.

Appends an additional sort order with the specified field in the specified order to the local partition sorting of the DataSet.

Overrides:

sortPartition in class DataSet<T>

Parameters:

field - The field expression referring to the field of the additional sort order of the local partition sorting.

order - The order of the additional sort order of the local partition sorting.

Returns:

The DataSet with sorted local partitions.

sortPartition

public <K> SortPartitionOperator<T> sortPartition(KeySelector<T,K> keyExtractor,
                                                  Order order)

Deprecated.

Description copied from class: DataSet

Locally sorts the partitions of the DataSet on the extracted key in the specified order. The DataSet can be sorted on multiple values by returning a tuple from the KeySelector.

Note that no additional sort keys can be appended to a KeySelector sort keys. To sort the partitions by multiple values using KeySelector, the KeySelector must return a tuple consisting of the values.

Overrides:

sortPartition in class DataSet<T>

Parameters:

keyExtractor - The KeySelector function which extracts the key values from the DataSet on which the DataSet is sorted.

order - The order in which the DataSet is sorted.

Returns:

The DataSet with sorted local partitions.

translateToDataFlow

protected SingleInputOperator<?,T,?> translateToDataFlow(Operator<T> input)

Deprecated.

Description copied from class: SingleInputOperator

Translates this operation to a data flow operator of the common data flow API.

Specified by:

translateToDataFlow in class SingleInputOperator<T,T,SortPartitionOperator<T>>

Parameters:

input - The data flow operator that produces this operation's input data.

Returns:

The translated data flow operator.
