ghettoq

Version:: 0.4.5

Introduction

ghettoq is a ghetto queue framework, used to implement Redis, MongoDB, Beanstalk, CouchDB, and Django database support for carrot

Installation

You can install ghettoq either via the Python Package Index (PyPI) or from source.

To install using pip,:

$ pip install ghettoq

To install using easy_install,:

$ easy_install ghettoq

If you have downloaded a source tarball you can install it by doing the following,:

$ python setup.py build
# python setup.py install # as root

Examples

>>> from ghettoq.simple import Connection
>>> import simplejson

>>> conn = Connection("redis", host="localhost", database=1)

>>> # Publishing messages
>>> q = conn.Queue("tasks")
>>> payload = {"name": "George Constanza"}
>>> q.put(simplejson.dumps(payload))

>>> # Consuming messages
>>> message = q.get()
>>> simplejson.loads(message)
{"name": "George Constanza"}

# Empty raises ghettoq.messaging.Empty >>> q.get() Empty

Using Django database support

If settings is already configured you don’t have to specify any connection options.

>>> from ghettoq.simple import Connection

>>> conn = Connection("database")
>>> queue = conn.Queue(name="tasks")
>>> queue.put("To whom it may concern")
>>> queue.get()
"To whom it may concern"

Using MongoDB support

If settings is already configured you don’t have to specify any connection options. The settings attrs used are:

BROKER_HOST: ‘127.0.0.1’ if not set
BROKER_PORT: 27017 if not set
BROKER_VHOST (Database Name): ‘ghettoq’ if not set

Collection name: “messages”… should be added support for BROKER_COL settings var?

>>> from ghettoq.simple import Connection

>>> conn = Connection("mongodb")
>>> queue = conn.Queue(name="tasks")
>>> queue.put("To whom it may concern")
>>> queue.get()
"To whom it may concern"

Using Beanstalk support

Requires the beanstalkc python library. If settings is already configured you don’t have to specify any connection options. The settings attrs used are:

BROKER_HOST: ‘localhost’ if not set
BROKER_PORT: 11300 if not set

BROKER_VHOST: ‘ghettoq’ if not set

>>> from ghettoq.simple import Connection

>>> conn = Connection("beanstalk")
>>> queue = conn.Queue(name="tasks")
>>> queue.put("To whom it may concern")
>>> queue.get()
"To whom it may concern"

Beanstalk also supports priorities. Jobs with lower priory numbers are executed before jobs with higher numbers. This number defaults to 0 and ranges from 0 to 2**32 - 1.

>>> queue.put("spam", priority=3)
>>> queue.get()
"spam"

Using CouchDB support

If settings is already configured you don’t have to specify any connection options. The settings attrs used are:

BROKER_HOST: ‘127.0.0.1’ if not set
BROKER_PORT: 5984 if not set
BROKER_VHOST (Database Name): ‘ghettoq’ if not set

View name: “ghettoq/messages”

>>> from ghettoq.simple import Connection

>>> conn = Connection("couchdb")
>>> queue = conn.Queue(name="tasks")
>>> queue.put("To whom it may concern")
>>> queue.get()
"To whom it may concern"

The couchdb backend requires the couchdb python module.
