> Currently, the Python UDF execution results are deserialized and then
> buffered in a collection when received from the Python worker. The
> deserialization could be deferred when sending the execution results to the
> downstream operator. That's to say, it buffers the serialized bytes instead
> of the deserialized Java objects in the buffer. This could reduce the memory
> footprint of the Java operator.
