I have been trying to get Celery task results to be routed to another process by making results persisted to a queue and another process can pick results from queue. So, have configured Celery as CELERY_RESULT_BACKEND = 'rpc', but still Python function returned value is not persisted to queue.
Not sure if any other configuration or code change required. Please help.
Here is the code example:
celery.py
from __future__ import absolute_import
from celery import Celery
app = Celery('proj',
broker='amqp://',
backend='rpc://',
include=['proj.tasks'])
# Optional configuration, see the application user guide.
app.conf.update(
CELERY_RESULT_BACKEND = 'rpc',
CELERY_RESULT_PERSISTENT = True,
CELERY_TASK_SERIALIZER = 'json',
CELERY_RESULT_SERIALIZER = 'json'
)
if __name__ == '__main__':
app.start()
tasks.py
from proj.celery import app
@app.task
def add(x, y):
return x + y
Running Celery as
celery worker --app=proj -l info --pool=eventlet -c 4
通过使用Pika(AMQP 0-9-1协议的Python实现 - https://pika.readthedocs.org )将结果发布回celeryresults渠道解决
