Class ChangelogCsvFormatFactory

java.lang.Object

org.apache.flink.table.examples.java.connectors.ChangelogCsvFormatFactory

All Implemented Interfaces:

DecodingFormatFactory<DeserializationSchema<RowData>>, DeserializationFormatFactory, Factory, FormatFactory

public final class ChangelogCsvFormatFactory
extends Object
implements DeserializationFormatFactory

The ChangelogCsvFormatFactory translates format-specific options to a format.

The FactoryUtil in SocketDynamicTableFactory takes care of adapting the option keys accordingly and handles the prefixing like changelog-csv.column-delimiter.

Because this factory implements DeserializationFormatFactory, it could also be used for other connectors that support deserialization formats such as the Kafka connector.

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.

                                                                           ReadableConfig formatOptions)

Description copied from interface: DecodingFormatFactory

Creates a format from the given context and format options.

The format options have been projected to top-level options (e.g. from format.ignore-errors to ignore-errors).
