Macul

Event driven worker consumer based on redis and utilize asyncio and uvloop to achieve high concurrency.

There are already exists celery, rq and anything else in python community, but the goal of this project is to allow us to create worker as simple as possible and has agnostic producer.

Usage Example:

Producer:

You can use any programming languages as long you LPUSH the event using key macul:default:task.

$ LPUSH macul:default:task '{"event": "SIGN_UP", "body": "{\"email\": "\john.doe@gmail.com"\, \"password\": \"test123$\"}"}'

Also the message is must have these two keys event with string value and body is JSON serializable or any primitive data type.

Consumer:

from macul import Macul


app = Macul()


@app.consumer(event_name='testing')
async def worker_testing(message):
    print('Consumed by: testing')
    print(message)


@app.consumer(event_name='notification')
async def worker_notification(message):
    print('Consumed by: notification')
    print(message)


if __name__ == '__main__':
    app.start()

TODO:

• Backoff / Retry mechanism.
• Auto reconnection if the redis die.
• Unit test.
• Publish on PyPI.

This project is still experimental and in heavy development..
