You write the demand to the database, and have a worker process execute it. Exactly like you'd do with celery.

Celery is a solution to scalability, not to any business problem in particular.

Years ago I ditched Celery in favour of using BLPOP with redis. It was multiple times faster than Celery. Is this still the case today? So with vanilla Redis you need less workers for same throughput; if you need more throughput, spawn multiple workers.
