Method Detail

createDecodingFormat

public DecodingFormat<DeserializationSchema<RowData>> createDecodingFormat(DynamicTableFactory.Context context,
                                                                           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).

Specified by:

createDecodingFormat in interface DecodingFormatFactory<DeserializationSchema<RowData>>

createEncodingFormat

public EncodingFormat<SerializationSchema<RowData>> createEncodingFormat(DynamicTableFactory.Context context,
                                                                         ReadableConfig formatOptions)

Description copied from interface: EncodingFormatFactory

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).

Specified by:

createEncodingFormat in interface EncodingFormatFactory<SerializationSchema<RowData>>

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

forwardOptions

public Set<ConfigOption<?>> forwardOptions()

Description copied from interface: FormatFactory

Returns a set of ConfigOption that are directly forwarded to the runtime implementation but don't affect the final execution topology.

Options declared here can override options of the persisted plan during an enrichment phase. Since a restored topology is static, an implementer has to ensure that the declared options don't affect fundamental abilities such as ChangelogMode.

For example, given a JSON format, if an option defines how to parse timestamps, changing the parsing behavior does not affect the pipeline topology and can be allowed. However, an option that defines whether the format results in a ProjectableDecodingFormat or not is not allowed. The wrapping connector and planner might not react to the changed abilities anymore.

Specified by:

forwardOptions in interface FormatFactory
