接口 DynamicTableSource.DataStructureConverter

所有超级接口:

RuntimeConverter, Serializable

封闭接口:

DynamicTableSource

public static interface DynamicTableSource.DataStructureConverter
extends RuntimeConverter

Converter for mapping between objects and Flink's internal data structures during runtime.

On request, the planner will provide a specialized (possibly code generated) converter that can be passed into a runtime implementation.

For example, a Row and its fields can be converted into RowData, or a (possibly nested) POJO can be converted into the internal representation for structured types.
