Interfaces

Interface	Description
org.apache.flink.legacy.table.connector.source.SourceFunctionProvider	This interface is based on the SourceFunction API, which is due to be removed. Use SourceProvider instead.
org.apache.flink.legacy.table.factories.StreamTableSinkFactory	This interface has been replaced by DynamicTableSinkFactory. The new interface creates instances of DynamicTableSink. See FLIP-95 for more information.
org.apache.flink.legacy.table.factories.StreamTableSourceFactory	This interface has been replaced by DynamicTableSourceFactory. The new interface creates instances of DynamicTableSource. See FLIP-95 for more information.
org.apache.flink.legacy.table.sinks.AppendStreamTableSink	This interface has been replaced by DynamicTableSink. The new interface consumes internal data structures. See FLIP-95 for more information.
org.apache.flink.legacy.table.sinks.RetractStreamTableSink	This interface has been replaced by DynamicTableSink. The new interface consumes internal data structures. See FLIP-95 for more information.
org.apache.flink.legacy.table.sinks.StreamTableSink	This interface has been replaced by DynamicTableSink. The new interface consumes internal data structures. See FLIP-95 for more information.
org.apache.flink.legacy.table.sinks.UpsertStreamTableSink	This interface has been replaced by DynamicTableSink. The new interface consumes internal data structures. See FLIP-95 for more information.
org.apache.flink.legacy.table.sources.StreamTableSource	This interface has been replaced by DynamicTableSource. The new interface produces internal data structures. See FLIP-95 for more information.
org.apache.flink.table.connector.sink.legacy.SinkFunctionProvider	This interface is based on the SinkFunction API, which is due to be removed. Use SinkV2Provider instead.

Classes

Class	Description
org.apache.flink.legacy.table.descriptors.RowtimeValidator	See Rowtime for details.
org.apache.flink.legacy.table.descriptors.SchemaValidator	See Schema for details.
org.apache.flink.legacy.table.sinks.OutputFormatTableSink	This interface has been replaced by DynamicTableSink. The new interface consumes internal data structures. See FLIP-95 for more information.
org.apache.flink.legacy.table.sources.InputFormatTableSource	This interface has been replaced by DynamicTableSource. The new interface produces internal data structures. See FLIP-95 for more information.
org.apache.flink.table.descriptors.OldCsvValidator	Use the RFC-compliant Csv format in the dedicated flink-formats/flink-csv module instead.
org.apache.flink.table.sinks.CsvAppendTableSinkFactory	The legacy CSV connector has been replaced by FileSink. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sinks.CsvBatchTableSinkFactory	The legacy CSV connector has been replaced by FileSink. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sinks.CsvTableSink	The legacy CSV connector has been replaced by FileSink. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sinks.CsvTableSinkFactoryBase	The legacy CSV connector has been replaced by FileSink. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sinks.LegacyCsvDynamicTableSinkFactory	The legacy CSV connector has been replaced by FileSink. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sinks.LegacyCsvDynamicTableSinkFactory.LegacyCsvDynamicTableSink	The legacy CSV connector has been replaced by FileSink. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sinks.LegacyCsvDynamicTableSinkOptions	The legacy CSV connector has been replaced by FileSink. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sources.CsvAppendTableSourceFactory	The legacy CSV connector has been replaced by FileSource. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sources.CsvBatchTableSourceFactory	The legacy CSV connector has been replaced by FileSource. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sources.CsvTableSource	The legacy CSV connector has been replaced by FileSource. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sources.CsvTableSourceFactoryBase	The legacy CSV connector has been replaced by FileSource. It is kept only to support tests for the legacy connector stack.
org.apache.flink.table.sources.format.CsvInputFormat
org.apache.flink.table.sources.format.RowCsvInputFormat	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.

Methods

Method	Description
org.apache.flink.legacy.table.descriptors.SchemaValidator.deriveTableSinkSchema(DescriptorProperties)	This method combines two separate concepts of table schema and field mapping. This should be split into two methods once we have support for the corresponding interfaces (see FLINK-9870).
org.apache.flink.legacy.table.factories.StreamTableSinkFactory.createStreamTableSink(Map<String, String>)	TableSinkFactory.Context contains more information, and already contains table schema too. Please use TableSinkFactory.createTableSink(Context) instead.
org.apache.flink.legacy.table.factories.StreamTableSourceFactory.createStreamTableSource(Map<String, String>)	TableSourceFactory.Context contains more information, and already contains table schema too. Please use TableSourceFactory.createTableSource(Context) instead.
org.apache.flink.table.api.bridge.java.StreamTableEnvironment.createTemporaryView(String, DataStream<T>, Expression...)	Use StreamTableEnvironment.createTemporaryView(String, DataStream, Schema) instead. In most cases, StreamTableEnvironment.createTemporaryView(String, DataStream) should already be sufficient. It integrates with the new type system and supports all kinds of DataTypes that the table runtime can consume. The semantics might be slightly different for raw and structured types.
org.apache.flink.table.api.bridge.java.StreamTableEnvironment.fromDataStream(DataStream<T>, Expression...)	Use StreamTableEnvironment.fromDataStream(DataStream, Schema) instead. In most cases, StreamTableEnvironment.fromDataStream(DataStream) should already be sufficient. It integrates with the new type system and supports all kinds of DataTypes that the table runtime can consume. The semantics might be slightly different for raw and structured types.
org.apache.flink.table.api.bridge.java.StreamTableEnvironment.toAppendStream(Table, Class<T>)	Use StreamTableEnvironment.toDataStream(Table, Class) instead. It integrates with the new type system and supports all kinds of DataTypes that the table runtime can produce. The semantics might be slightly different for raw and structured types. Use toDataStream(DataTypes.of(TypeInformation.of(Class))) if TypeInformation should be used as source of truth.
org.apache.flink.table.api.bridge.java.StreamTableEnvironment.toRetractStream(Table, Class<T>)	Use StreamTableEnvironment.toChangelogStream(Table, Schema) instead. It integrates with the new type system and supports all kinds of DataTypes and every ChangelogMode that the table runtime can produce.
org.apache.flink.table.sources.CsvTableSource.Builder.field(String, TypeInformation<?>)	This method will be removed in future versions as it uses the old type system. It is recommended to use CsvTableSource.Builder.field(String, DataType) instead which uses the new type system based on DataTypes. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
