trunk 0.2.0

Making postgres listen/notify easier.

Installing

To install :

pip install trunk

Usage

Trunk tries to be as simple as possible

t = Trunk("postgres://localhost/noclue")
for channel, payload in t.notifications("clues"):
    print channel, payload
t.notify("clues", "chandelier")
t.unlisten("clues")

Celery

Trunk provides a Kombu transport, that allows you to use trunk with Celery, to do so, configure Celery with :

BROKER_URL = 'trunk.transport.Transport://localhost/database'

Limitations

For now, and since LISTEN/NOTIFY behavior is not strictly speaking a queue, if you have more than one celery worker (but you can use worker concurrency), each worker will receive every job send.
