My idea is to let one `Pickler` instance only handle data of the same schema. IIUC the Python UDF operator needs to send the input (values of (c1, c2)) to Python, run the UDF, and send back the UDF result (values of (c3, c4)). Since the `Pickler` instance is used to serialize both the input and output data, the bug happens. Do I understand it correctly? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
