pysqes

Simple queue service for python using SQS and boto.

Usage

In order to create a task you can use the SQSTask class to create an instance that include a function decorator which can be sent to the queue when you run the delay method that will be added to the function. The delay function takes the parameters that will be used by the worker when it actually executes the task.

from boto.sqs.connection import SQSConnection
from pysqes.task import Task

conn = SQSConnection('ACCESS_KEY', 'SECRET_KEY')
queue = Queue(conn, 'pysqes_test', backend=backend)

def add(a, b):
    return a + b

# this will submit a job to the queue
queue.enqueue(add, 1, 2)

You can run the task by using the work method included in the SQSWorker class, all you need to do is create a worker instance.

from boto.sqs.connection import SQSConnection
from pysqes.runners.gevent_runner import GeventRunner
from pysqes.worker import Worker

conn = SQSConnection('ACCESS_KEY', 'SECRETE_KEY')
runner = GeventRunner()
queue = Queue(conn, 'pysqes_test', backend=backend)
worker = Worker(queue, runner=runner)

worker.work()

New in 0.2

Worker Runners

Pysqes now supports having different runners, the default one is the process runner, which will spawn a new a process and run the task in it. We also have a gevent runner, which you can use by using the gevent flag in the command line and set the number of threads you would like to have running. Note: It has only been tested with gevent 1.0

Command line scripts

Pysqes now comes with command line scripts. The worker command will be the only one available for this version, but task and peek commands may be coming to 0.3.

pysqes worker --gevent --workerpath=/home/user/pysqesproj/ --config=pysqesconfig --configpath=/home/user/pysqesproj/settings/

Running the tests

If you are using python 2.7 you can run the unit tests by using the new discover runner included in the unittest module:

python -m unittest discover -s tests

or you can just run each unit test individually.

Coming in 0.3

• New command line scripts.
• Tests for command line scripts.
• Better logging.
