bcbecker / Redis-Task-Queue

Simple task queue with RQ and Redis as the broker.

Redis-Task-Queue

Simple task queue with rq (celery later) to see how background tasks operate with Redis as a message broker.

Setup

Ensure python 3.9 is installed.

Install requirements:

pip install -r requirements.txt

Or, access virtual environment:

pip install pipenv
pipenv shell

Running the Server

In separate terminal windows, you must set up Redis (needs to be installed locally), run an rq worker, and run the flask server. Linux/Mac:

redis-server

rq worker

cd task_queue
python app.py

Making Requests

Go to the /task endpoint (http://127.0.0.1:5000/task). You should see that there are no tasks in the queue. Add to the URL your query: '?n=' and hit enter. You should see it added to the queue, and in your flask terminal, the prints defined in the simulated_task method. You can either update n or just keep refreshing to keep adding tasks.

For example: http://127.0.0.1:5000/task?n=hey should show something like:

567a103f-17bd-4618-905e-7a45dd2bc01f added to queue at 2021-09-29 03:18:57.394759 ------ 0 tasks in queue

You see zero, because the only task that was in the queue is being executed. Refresh the page and you'll have multiple tasks lined up.
