FastAPI: xử lý việc nặng ở background với BackgroundTasks, client không phải chờ
Khi một API phải làm việc chậm như gửi email, xử lý file hay gọi dịch vụ bên ngoài, đừng bắt client đứng chờ. Trong FastAPI, bạn chỉ cần khai báo thêm tham số background_tasks: BackgroundTasks trong endpoint và gọi background_tasks.add_task(...) — response được trả về ngay lập tức, còn việc nặng sẽ chạy ở background ngay sau đó. Kỹ thuật này áp dụng cho mọi tác vụ "chậm nhưng không cần kết quả ngay": gửi email, push notification, ghi log, xử lý file upload.

Work that survives a client disconnect is the sleeper topic here. Most first agent endpoints die the moment someone closes the tab mid-stream, and BackgroundTasks won't outlive a worker restart.

Also, I decided to schedule only one reminder (of the given kind) into the future for each habit and scheduled background task that should schedule the next ones if needed every 30 minutes. I don’t know what the best practice is here, tbh.

The problem with that is when the user doesn’t open the app for a day, I don’t have a way for scheduling the next reminder. I could use a background task for that, but there is no guarantee it’ll be run - thanks 🍎.

O mais simples que consigo imaginar é rodar em uma task independente no mesmo processo que está servindo o seu backend.
No FastAPI tem as BackgroundTasks pra isso, no Node vc pode só lançar uma Promise e cuidar pro processo não encerrar enquanto tiver alguma pendente (tem técnicas pra isso).

The BackgroundTasks framework doesn't support macOS. There's `NSBackgroundActivityScheduler`, but the API is totally different.

なるほど、BackgroundTasksに行く前にfinallyまで行っちゃうから、裏でプールがないっていうんだ。考えてみればそりゃそうだよなぁ。時間がかかるから裏で動かしてるのであって、その前にPOSTが終わるようにしているんだもの。確かに、プールを閉じるんじゃなくてconnを返すだけだとちゃんと動くんだ。つまり、やっぱりclassは表裏共通。
