Hi,

Unfortunately the Akka ZeroMQExtension doesn't expose the XPUB/XSUB socket 
types, since the zeromq scala bindings that it uses doesn't expose them. If you 
only want to proxy things, then maybe you can use the jzmq java bindings 
directly?

Hello,

I have spent a day or so trying to figure out where the XPUB/XSUB stuff and the 
poll capability are in the zeromq bindings or in akka ZeroMQExtension. However 
I am not having any luck.

In zeroMQ and other language bindings you can do things like:

    ctx = zmq.Context.instance()
frontend = ctx.socket(zmq.SUB)
frontend.bind("tcp://*:5557")
backend = ctx.socket(zmq.XPUB)
backend.bind("tcp://*:5558")

# Subscribe to every single topic from publisher
frontend.setsockopt(zmq.SUBSCRIBE, b"")

# Store last instance of each topic in a cache
cache = {}

# We route topic updates from frontend to backend, and
# we handle subscriptions by sending whatever we cached,
# if anything:
poller = zmq.Poller()
poller.register(frontend, zmq.POLLIN)
poller.register(backend, zmq.POLLIN)

    # so on and so on

Then you can proxy things between the frontend and the backend.

How does one go about doing this in Scala/Akka?

Thanks!
OD
