Daniel Camacho commented on AVRO-1375:
--------------------------------------
I have a possible idea that we can discuss:
- Would it be possible to Wrap NettyTransceiver Java Class in Python with any
Java Callers from Python ( Pyjnius/Jnius, or Py4j) and create a
NettyTransceiver Object in Python?
> Python to Java RPC call error
