mengxr edited a comment on issue #24734: [SPARK-27870][SQL][PySpark] Flush each batch for pandas UDF (for improving pandas UDFs pipeline) URL: https://github.com/apache/spark/pull/24734#issuecomment-497111995 If a buffered writer is used, it doesn't flush data to output stream immediately. So the reader on the other side, even trying to read the data from the stream at all time, cannot see the data until the buffered writer decides to flush.
