@Deprecated
@Public
public class DataSink<T>
extends Object

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.

An operation that allows storing data results.

Constructor Detail

DataSink

public DataSink(DataSet<T> data,
                org.apache.flink.api.common.io.OutputFormat<T> format,
                org.apache.flink.api.common.typeinfo.TypeInformation<T> type)

Deprecated.

Method Detail

getFormat

@Internal
public org.apache.flink.api.common.io.OutputFormat<T> getFormat()

Deprecated.

getType

@Internal
public org.apache.flink.api.common.typeinfo.TypeInformation<T> getType()

Deprecated.

getDataSet

@Internal
public DataSet<T> getDataSet()

Deprecated.

withParameters

public DataSink<T> withParameters(org.apache.flink.configuration.Configuration parameters)

Deprecated.

Pass a configuration to the OutputFormat.

Parameters:

parameters - Configuration parameters

sortLocalOutput

@Deprecated
@PublicEvolving
public DataSink<T> sortLocalOutput(int field,
                                   org.apache.flink.api.common.operators.Order order)

Deprecated.

Use DataSet.sortPartition(int, Order) instead

Sorts each local partition of a Tuple data set on the specified field in the specified Order before it is emitted by the output format.

Note: Only tuple data sets can be sorted using integer field indices.

The tuple data set can be sorted on multiple fields in different orders by chaining sortLocalOutput(int, Order) calls.

Parameters:

field - The Tuple field on which the data set is locally sorted.

order - The Order in which the specified Tuple field is locally sorted.

Returns:

This data sink operator with specified output order.

See Also:

Tuple, Order

sortLocalOutput

@Deprecated
@PublicEvolving
public DataSink<T> sortLocalOutput(String fieldExpression,
                                   org.apache.flink.api.common.operators.Order order)

Deprecated.

Use DataSet.sortPartition(String, Order) instead

Sorts each local partition of a data set on the field(s) specified by the field expression in the specified Order before it is emitted by the output format.

Note: Non-composite types can only be sorted on the full element which is specified by a wildcard expression ("*" or "_").

Data sets of composite types (Tuple or Pojo) can be sorted on multiple fields in different orders by chaining sortLocalOutput(String, Order) calls.

Parameters:

fieldExpression - The field expression for the field(s) on which the data set is locally sorted.

order - The Order in which the specified field(s) are locally sorted.

Returns:

This data sink operator with specified output order.

See Also:

Order

getParameters

public org.apache.flink.configuration.Configuration getParameters()

Deprecated.

Returns:

Configuration for the OutputFormat.

name

public DataSink<T> name(String name)

Deprecated.

translateToDataFlow

protected org.apache.flink.api.common.operators.GenericDataSinkBase<T> translateToDataFlow(org.apache.flink.api.common.operators.Operator<T> input)

Deprecated.

toString

public String toString()

Deprecated.

Overrides:

toString in class Object

getParallelism

public int getParallelism()

Deprecated.

Returns the parallelism of this data sink.

Returns:

The parallelism of this data sink.

setParallelism

public DataSink<T> setParallelism(int parallelism)

Deprecated.

Sets the parallelism for this data sink. The degree must be 1 or more.

Parameters:

parallelism - The parallelism for this data sink. A value equal to ExecutionConfig.PARALLELISM_DEFAULT will use the system default.

Returns:

This data sink with set parallelism.

getMinResources

@PublicEvolving
public org.apache.flink.api.common.operators.ResourceSpec getMinResources()

Deprecated.

Returns the minimum resources of this data sink. If no minimum resources have been set, this returns the default resource profile.

Returns:

The minimum resources of this data sink.

getPreferredResources

@PublicEvolving
public org.apache.flink.api.common.operators.ResourceSpec getPreferredResources()

Deprecated.

Returns the preferred resources of this data sink. If no preferred resources have been set, this returns the default resource profile.

Returns:

The preferred resources of this data sink.
