Class PrintTableSinkFactory

java.lang.Object

org.apache.flink.table.factories.PrintTableSinkFactory

All Implemented Interfaces:

DynamicTableFactory, DynamicTableSinkFactory, Factory

@PublicEvolving
public class PrintTableSinkFactory
extends Object
implements DynamicTableSinkFactory

Print table sink factory writing every row to the standard output or standard error stream. It is designed for: - easy test for streaming job. - very useful in production debugging.

Four possible format options: PRINT_IDENTIFIER:taskId> output <- PRINT_IDENTIFIER provided, parallelism > 1 PRINT_IDENTIFIER> output <- PRINT_IDENTIFIER provided, parallelism == 1 taskId> output <- no PRINT_IDENTIFIER provided, parallelism > 1 output <- no PRINT_IDENTIFIER provided, parallelism == 1

output string format is "$RowKind(f0,f1,f2...)", example is: "+I(1,1)".

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.

Specified by:

optionalOptions in interface Factory

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.

Specified by:

createDynamicTableSink in interface DynamicTableSinkFactory
