org.apache.flink.connector.blackhole.table.BlackHoleTableSinkFactory

All Implemented Interfaces:

DynamicTableFactory, DynamicTableSinkFactory, Factory

@Internal
public class BlackHoleTableSinkFactory
extends Object
implements DynamicTableSinkFactory

Black hole table sink factory swallowing all input records. It is designed for: - high performance testing. - UDF to output, not substantive sink. Just like /dev/null device on Unix-like operating systems.

Method Detail

factoryIdentifier

public String factoryIdentifier()

Description copied from interface: Factory

Returns a unique identifier among same factory interfaces.

For consistency, an identifier should be declared as one lower case word (e.g. kafka). If multiple factories exist for different versions, a version should be appended using "-" (e.g. elasticsearch-7).

Specified by:

factoryIdentifier in interface Factory

requiredOptions

public Set<ConfigOption<?>> requiredOptions()

Description copied from interface: Factory

Returns a set of ConfigOption that an implementation of this factory requires in addition to Factory.optionalOptions().

See the documentation of Factory for more information.

Specified by:

requiredOptions in interface Factory

optionalOptions

public Set<ConfigOption<?>> optionalOptions()

Description copied from interface: Factory

Returns a set of ConfigOption that an implementation of this factory consumes in addition to Factory.requiredOptions().

See the documentation of Factory for more information.

createDynamicTableSink

public DynamicTableSink createDynamicTableSink(DynamicTableFactory.Context context)

Description copied from interface: DynamicTableSinkFactory

Creates a DynamicTableSink instance from a CatalogTable and additional context information.

An implementation should perform validation and the discovery of further (nested) factories in this method.
