README
RQ (_Redis Queue_) is a simple Python library for queueing jobs and processing
them in the background with workers. It is backed by Redis and it is designed
to have a low barrier to entry. It should be integrated in your web stack
easily.RQ requires Redis >= 3.0.0.

## Support RQ
If you find RQ useful, please consider supporting this project via [Tidelift](https://tidelift.com/subscription/pkg/pypi-rq?utm_source=pypi-rq&utm_medium=referral&utm_campaign=readme).
## Getting started
First, run a Redis server, of course:
```console
$ redis-server
```To put jobs on queues, you don't have to do anything special, just define
your typically lengthy or blocking function:```python
import requestsdef count_words_at_url(url):
"""Just an example function that's called async."""
resp = requests.get(url)
return len(resp.text.split())
```Then, create an RQ queue:
```python
from redis import Redis
from rq import Queuequeue = Queue(connection=Redis())
```And enqueue the function call:
```python
from my_module import count_words_at_url
job = queue.enqueue(count_words_at_url, 'http://nvie.com')
```Scheduling jobs are also similarly easy:
```python
# Schedule job to run at 9:15, October 10th
job = queue.enqueue_at(datetime(2019, 10, 10, 9, 15), say_hello)# Schedule job to run in 10 seconds
job = queue.enqueue_in(timedelta(seconds=10), say_hello)
```Retrying failed jobs is also supported:
```python
from rq import Retry# Retry up to 3 times, failed job will be requeued immediately
queue.enqueue(say_hello, retry=Retry(max=3))# Retry up to 3 times, with configurable intervals between retries
queue.enqueue(say_hello, retry=Retry(max=3, interval=[10, 30, 60]))
```For a more complete example, refer to the [docs][d]. But this is the essence.
### The worker
To start executing enqueued function calls in the background, start a worker
from your project's directory:```console
$ rq worker --with-scheduler
*** Listening for work on default
Got count_words_at_url('http://nvie.com') from default
Job result = 818
*** Listening for work on default
```That's about it.
## Installation
Simply use the following command to install the latest released version:
pip install rq
If you want the cutting edge version (that may well be broken), use this:
pip install git+https://github.com/rq/rq.git@master#egg=rq

This project has been inspired by the good parts of [Celery][1], [Resque][2]
and [this snippet][3], and has been created as a lightweight alternative to the
heaviness of Celery or other AMQP-based queueing implementations.[d]: http://python-rq.org/
