A convenience wrapper for Gearman clients and workers in Django/Python. Designed and tested against Gearman 1.14.

7 years after


django-gearman is a convenience wrapper for the Gearman Python Bindings.

With django-gearman, you can code jobs as well as clients in a Django project with minimal overhead in your application. Server connections etc. all take place in django-gearman and don't unnecessarily clog your application code.


It's the same for both the client and worker instances of your django project:

pip install -e git://

Add django_gearman to the INSTALLED_APPS section of

Specify the following settings in your local file:

# One or more gearman servers


Registering jobs

Create a file in any of your django apps, and define as many jobs as functions as you like. The jobs must accept a single argument as passed by the caller and must return the result of the operation (if there is a result).

This module implements transparent pickling, so workers both send and receive native python datatypes.

Mark each of these functions as gearman jobs by decorating them with django_gearman.decorators.gearman_job.

For an example, look at the gearman_example app's file.

Starting a worker

To start a worker, run python gearman_worker. It will start serving all registered jobs.

To spawn more than one worker (if, e.g., most of your jobs are I/O bound), use the -w option:

python gearman_worker -w 5

will start five workers.

Since the process will keep running while waiting for and executing jobs, you probably want to run this in a screen session or similar.


To make your workers work, you need a client app passing data to them. Create and instance of the django_gearman.GearmanClient class and execute it:

from django_gearman import DjangoGearmanClient
client = DjangoGearmanClient()
sentence = "Simple Example"
completed_job_request = client.submit_job("gearman_example.reverse", sentence))
print "Result: '%s'" % completed_job_request.result

The notation for the task name is appname.jobname.

Dispatching a background event without waiting for the result is easy as well:

completed_job_request = client.submit_job("gearman_example.reverse", wait_until_complete=False))

For a live example look at the gearman_example app, in the management/commands/ file.

For more information, see the gearman documentation:

Example App

For a full, working, example application, add gearman_example to your INSTALLED_APPS, then run a worker in one shell:

python gearman_worker -w 4

and execute the example app in another:

python gearman_example_client

You can see the client sending data and the worker(s) working on it.
