I'm not very expert on the topic, however I used redis for queueing slow tasks before but in a PHP project.
Currently in my django project I have a few mutations and queries that totally fit to be put as async background jobs as they really cause the system to be sluggish. I also have this application hosted on Heroku, and Heroku suggests using background workers with Redis.

So I started looking into it and I found a few libraries and tutorials for integrating django with redis, but I get stuck at the graphene/graphql part. Not sure if this is even doable with graphene. If so, anyone can point it out the way. If not, what would be a good solution to my problem?
