> You can do the same with python's msgpack as the C# version
You can't. The unpacker in msgpack for Python only reads full objects. The C# version lets me go into and out of streaming at will and even skip past objects without reading them into memory. The only thing the Python version of msgpack can do with the unpacker is buffering up bytes internally until an object is ready. That object however could still expand into a 10GB blob of data which I would then have to postprocess.
