ZeroMQ is a high-performance asynchronous messaging library.

Key Features

  • Supports various messaging patterns (pub/sub, request/reply, etc.)
  • No central broker, can be used for direct inter-process communication
  • Very fast and lightweight

Basic Usage

import zmq

context = zmq.Context()
socket = context.socket(zmq.REP)
socket.bind("tcp://*:5555")

while True:
    message = socket.recv()
    print(f"Received request: {message}")
    socket.send(b"World")
