@Deprecated @Internal public interface TableSink<T>
Deprecated.

    getOutputType()
    Deprecated.
    This method will be removed in future versions as it uses the old type system.

  • Method Details

    • getConsumedDataType

      default DataType getConsumedDataType()
      Deprecated.
      Returns the data type consumed by this TableSink.
      Returns:
      The data type expected by this TableSink.

    • getOutputType

      @Deprecated default org.apache.flink.api.common.typeinfo.TypeInformation<T> getOutputType()
      Deprecated.
      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()
      Deprecated.
      Returns the schema of the consumed table.
      Returns:
      The TableSchema of the consumed table.

    • getFieldNames

      @Deprecated default String[] getFieldNames()
      Deprecated.
      Use the field names of getTableSchema() instead.

    • getFieldTypes

      @Deprecated default org.apache.flink.api.common.typeinfo.TypeInformation<?>[] getFieldTypes()
      Deprecated.
      Use the field types of getTableSchema() instead.

    • configure

      @Deprecated TableSink<T> configure(String[] fieldNames, org.apache.flink.api.common.typeinfo.TypeInformation<?>[] fieldTypes)
      Deprecated.
      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.
      Parameters:
      fieldNames - The field names of the table to emit.
      fieldTypes - The field types of the table to emit.
      Returns:
      A copy of this TableSink configured with the field names and types of the table to emit.
