Building from a git checkout requires a C compiler, Python, Cython, and the
nmsg library to be installed first. Distribution tarballs ship with a copy of
the Cython-generated code and do not require Cython to actually be installed.
pynmsg is built by running
python setup.py build
Some notes on performance. In particular, Python isn't great at receiving nmsgs off of the network at high rates, and processing them reliably.
Reading from a socket suffers about 75% loss (our test sent 1723300 messages, pynmsg recvd ~400k), so although the ability to read from the network exists, but transport is UDP, this Python library is not appropriate for receiving a high volume container stream.
As a point of comparison, running the same test: using nmsgtool to read from a file, write to a localhost socket but instead of Python, using another nmsgtool reading from the localhost socket:
writer sends: 1723300 messages
