Install

1. Choosing and installing a message transport (broker). !!!something about RabbitMQ!!!
2. Celery install is pretty easy.
3. Monitor Celery in Real Time. Flower is a real-time web-based monitor for Celery. Using Flower, you could easily monitor your task progress and history. As before, can use pip to install Flower:

Basic project

Below is the structure of our demo project.

1. Leaev __init__.py empty.
2. Add the following code in celery.py
3. In the tasks.py file define our tasks
4. Add the following code in job.py
5. Open terminal, let's call it Terminal 1

6. Open second terminal, let's call it Terminal 2

from 13:53:36 to 13:55:37 (2m 01s)

7. The same time as in Terminal 2 we should be able to observe in Terminal 1 results similar to the following

8. Run Flower. Having Celery still running in Terminal 1 open new terminal Terminal 3 and run Flower in it

9. Open second terminal, Terminal 2 and run our job

This time check what Flower allows us to control.

Notice, that acording to Celery settings report displayed at start

only one task is executed at a time.

As previously, in Terminal 1 we should see the following results

10. To allow (or force) Celery to execute more than one task at a time, use -c option (in Terminal 1 press Control + C to stop running Celery)
11. Now execution of our job should be much more effective (use Terminal 2)

from 14:25:08 to 14:25:39 (31s))
