Question

我正试图限制芹菜中的任务。我为它创建了一个简单的项目。但它不起作用。

这是我的计划：

celery.py

from __future__ import absolute_import

from celery import Celery
from celery.task.control import rate_limit

app = Celery('proj',
             broker='amqp://',
             backend='amqp://',
             include=['proj.tasks'])

# Optional configuration, see the application user guide.
app.conf.update(
    CELERY_TASK_RESULT_EXPIRES=3600,
)

# app.control.rate_limit('proj.tasks', '2/m')
rate_limit("proj.tasks", "2/m")
if __name__ == '__main__':
    app.start()

tasks.py

from __future__ import absolute_import

from proj.celery import app

@app.task
def add(x, y):
    return x + y

项目结构：

.
└── proj
    ├── celery.py
    ├── __init__.py
    └── tasks.py

作业：

from proj.tasks import *
add.delay(1,2)
add.delay(2,1)
add.delay(2,2)
add.delay(2,3)
add.delay(3,4)

输出：

我知道为什么会收到此错误？这可能有什么问题？

感谢任何帮助。

感谢您不要对这个问题进行投票。

Answer 1

尝试为任务添加速率限制似乎是错误消息的问题猜测。

rate_limit("proj.tasks.add","2/m")

感谢。

芹菜率限制不起作用
