Kanggo robust, durable background jobs (ngliwati lightweight BackgroundTasks FastAPI), sampeyan nggunakne real task queue: Celery (standard established) utawa ARQ (modern async-native queue). Iki ngjalanke heavy, retryable, scheduled work ing proses worker pisah, diganti dening broker kaya Redis.
Napa iku penting
BackgroundTasks runs in the web process → NO persistence (lost on crash), NO retries,
NO scheduling, and heavy work ties up the worker. Fine only for quick fire-and-forget.
For durable/critical/heavy/scheduled jobs → use a real task queue (Celery / ARQ).
