            final RowType rowType = (RowType) physicalDataType.getLogicalType();
            final CsvSchema schema = buildCsvSchema(rowType, formatOptions);
            final RowDataToCsvConverter converter = RowDataToCsvConverters.createRowConverter(rowType);

            final RowDataToCsvConverter.RowDataToCsvFormatConverterContext converterContext = new RowDataToCsvConverter.RowDataToCsvFormatConverterContext(mapper, container);
            return out -> CsvBulkWriter.forSchema(mapper, schema, converter, converterContext, out);
        }
