Distributed message queue based on Redis

Project description

Styx is a simple library that turns a bunch of standalone Redis servers into a powerful distributed queue. The redis servers don’t need any special configuration or even be aware of each other in any way. The messages are loosely ordered. A java version can be found here. The java and python versions are compatible - i.e. messages published by one client can be read by the other client.

Install

pip install styx

Quickstart

#!/usr/bin/env python
# encoding: utf-8

import styx

# Define the Redis host locations (the default port is 6379)
hosts = [ "redis1.example.com", "redis2.example.com:8080", "redis3.example.com" ]

connection = styx.Styx(hosts, db=3) # default db is 0
# If a queue doesn't exist, it will be created automatically
q = connection.get_queue("myTestQueue")
q.put("Hello")
q.put("World")
q.put("Message1234")

q.get() # returns "Hello"
q.get() # returns "World"

# Check how many messages are left in the queue
q.size() # returns 1

# Delete this queue
connection.delete_queue(q)

Unit Tests

To run unit tests, make sure you have 3 redis instances running on localhost at ports 6700, 6701, 6702.
