已过时。

This interface has been replaced by DynamicTableSink. The new interface consumes internal data structures. See FLIP-95 for more information.

@PublicEvolving
public interface TableSink<T>

A TableSink specifies how to emit a table to an external system or location.

The interface is generic such that it can support different storage locations and formats.

方法概要

限定符和类型	方法和说明
TableSink<T>	configure(String[] fieldNames, org.apache.flink.api.common.typeinfo.TypeInformation<?>[] fieldTypes) 已过时。 This method will be dropped in future versions. It is recommended to pass a static schema when instantiating the sink instead.
default DataType	getConsumedDataType() 已过时。 Returns the data type consumed by this TableSink.
default String[]	getFieldNames() 已过时。 Use the field names of getTableSchema() instead.
default org.apache.flink.api.common.typeinfo.TypeInformation<?>[]	getFieldTypes() 已过时。 Use the field types of getTableSchema() instead.
default org.apache.flink.api.common.typeinfo.TypeInformation<T>	getOutputType() 已过时。 This method will be removed in future versions as it uses the old type system. It is recommended to use getConsumedDataType() 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.
default TableSchema	getTableSchema() 已过时。 Returns the schema of the consumed table.

getConsumedDataType

default DataType getConsumedDataType()

已过时。

Returns the data type consumed by this TableSink.

返回:

The data type expected by this TableSink.

getOutputType

@Deprecated
default org.apache.flink.api.common.typeinfo.TypeInformation<T> getOutputType()

已过时。 This method will be removed in future versions as it uses the old type system. It is recommended to use getConsumedDataType() 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.

getTableSchema

default TableSchema getTableSchema()

已过时。

Returns the schema of the consumed table.

返回:

The TableSchema of the consumed table.

getFieldNames

@Deprecated

configure

@Deprecated
TableSink<T> configure(String[] fieldNames,
                                   org.apache.flink.api.common.typeinfo.TypeInformation<?>[] fieldTypes)

已过时。 This method will be dropped in future versions. It is recommended to pass a static schema when instantiating the sink instead.

Returns a copy of this TableSink configured with the field names and types of the table to emit.

参数:

fieldNames - The field names of the table to emit.

fieldTypes - The field types of the table to emit.

返回:

A copy of this TableSink configured with the field names and types of the table to emit.
