Documentation Status

A gevent based python client for NSQ distributed messaging platform.

Features include:

  • Free software: BSD license
  • Documentation: https://gnsq.readthedocs.org
  • Battle tested on billions and billions of messages </sagan>
  • Based on gevent for fast concurrent networking
  • Fast and flexible signals with Blinker
  • Automatic nsqlookupd discovery and back-off
  • Support for TLS, DEFLATE, and Snappy
  • Full HTTP clients for both nsqd and nsqlookupd

Installation

At the command line:

$ easy_install gnsq

Or even better, if you have virtualenvwrapper installed:

$ mkvirtualenv gnsq
$ pip install gnsq

Currently there is support for Python 2.7+, Python 3.4+ and PyPy.

Usage

First make sure nsq is installed and running. Next create a producer and publish some messages to your topic:

import gnsq

producer = gnsq.Producer('localhost:4150')

producer.publish('topic', 'hello gevent!')
producer.publish('topic', 'hello nsq!')

Then create a Consumer to consume messages from your topic:

consumer = gnsq.Consumer('topic', 'channel', 'localhost:4150')

@consumer.on_message.connect
def handler(consumer, message):
    print 'got message:', message.body

consumer.start()

Compatibility

For NSQ 1.0 and later, use the major version 1 (1.x.y) of gnsq.

For NSQ 0.3.8 and earlier, use the major version 0 (0.x.y) of the library.

The recommended way to set your requirements in your setup.py or requirements.txt is:

# NSQ 1.x.y
gnsq>=1.0.0

# NSQ 0.x.y
gnsq<1.0.0

Dependencies

Optional snappy support depends on the python-snappy package which in turn depends on libsnappy:

# Debian
$ sudo apt-get install libsnappy-dev

# Or OS X
$ brew install snappy

# And then install python-snappy
$ pip install python-snappy
