Project Description

Carotte is a very lightweight Celery on zmq.


pip install carotte

Getting started

Create your

from carotte import Carotte

my_app = Carotte()

def hello_world(name):
    return 'Hello %s!' % name

Run your worker (default on “tcp://”):

carotte worker --app app:my_app

Run tasks:

>>> from app import hello_world
>>> t = hello_world.delay(['Carotte'])
>>> t.success
>>> True
>>> t.result
>>> 'Hello Carotte!'

Or run a client (if don’t have tasks on your system):

>>> from carotte import Client
>>> client = Client()
>>> task = client.run_task('hello_world', ['Carotte'])
>>> task.success
>>> True
>>> task.result
>>> 'Hello Carotte!'

Scheduled tasks

Carotte is not a scheduler, its an asynchronous tasks runner. But you can really set up scheduled tasks with schedule.


import requests
from carotte import Carotte

my_app = Carotte()

def get(url):
    r = requests.get(url)
    if r.status_code != 200:
        # Do stuff
        return False
    return True


import time
import schedule
from app import get

schedule.every(10), '')

while True:

Run your worker and your scheduler:

carotte worker --app app:my_app
