In which manner zeroMQ read form multiple connections?

Question

I want to know in which manner zeroMQ read form multiple connections ?

For example:

• If I have a server which is connected to multiple clients and receiving data at the same time from all the clients which of the one it will read first?
• Is it round robin or some other algorithm?

Answer 1

Use pub-sub routine, Python example:

#Publishing script
import zmq
ctx = zmq.Context()
socket_publish = ctx.socket(zmq.PUB)
socket_publish.bind("tcp://*:7787") #define socket for publishing

#subscribing script(s)
ctx = zmq.Context()
s = ctx.socket(zmq.SUB)
s.connect("tcp://127.0.0.1:7787") #connect to the socket multiple times
s.setsockopt(zmq.SUBSCRIBE,'')
msg  = s.recv()
