   @pan3793 , the iceberg flink sink underlying will write  `RowData` into avro/parquet/orc files , no matter which data types you    are writing. So we provided the `MapFunction<T, RowData> mapper` to convert your own data type into `RowData`. So you might need to provide a function to convert `GenericRecord` to `RowData`.   The `TypeInformation<RowData>`  specify your data type for inputstream . 
   
   We have provided an unit test to write `row` stream to iceberg sink, you may want to take a look. https://github.com/apache/iceberg/blob/master/flink/src/test/java/org/apache/iceberg/flink/sink/TestFlinkIcebergSink.java#L153 .
