Недавно делал быстрый прототип асинхронного приложения в котором требовалось вызывать много синхронного кода. Да, я знаю, что это не лучший дизайн, но нужно было быстрое решение на один процесс и без очередей. Поэтому я выполнял код в потоках. Выглядело это примерно так: from fastapi.concurrency import run_in_threadpool async def execute(data: DataRequest) -> DataResponse: try: result = await run_in_threadpool(sync_function, data) return DataResponse(data=result) except Exception as e: return DataResponse( error=str(e), success=False, ) В общем работает нормально. Для всех вызовов под капотом используется общий тредпул, всё работает предсказуемо. Но потребовалось изменить количество запускаемых в пуле потоков (по умолчанию создается 40 воркеров). Так как дело происходит с FastAPI, делается это через lifespan используя настройки anyio: import anyio @asynccontextmanager async def lifespan(app: FastAPI): limiter = anyio.to_thread.current_default_thread_limiter() limiter.total_tokens = 100 yield # если вдруг нужно вернуть обратно limiter.total_tokens = 40 Зачем менять количество воркеров? - уменьшить, если оперативки мало (один тред занимает ~8мб) - увеличить чтобы выдержать нагрузку Если есть предложения получше при тех же вводных - предлагайте😉 #async

🌎 The Falkland Islands are home to the only known population of the Cobb’s wren, a small brown bird found nowhere else on Earth. These birds thrive in predator-free habitats, showing how isolated islands can protect unique species from extinction. ✨ #biodiversity⚡#islands⚡#birds 👉subscribe Interesting Planet

🌎 Border oddities abound in Earth’s geography! The Diomede Islands, just 4 km apart in the Bering Strait, belong to different countries and are separated by the International Date Line, meaning they are 21 hours apart in time despite being visible from each other. ✨ #geography⚡#borders⚡#islands 👉subscribe Interesting Planet

🚤Nusa Penida could be home to a floating hospital 🏥 Nusa Penida leaders are proposing a water ambulance service to respond quickly to emergencies. 🚨 There are currently no major hospitals on the islands of Nusa Penida, Nusa Lembongan and Nusa Ceningan near Bali. The small clinics that do exist are unable to treat emergencies and patients have to be brought to Bali by boat or evacuated by helicopter. @BaliNews #goodnews#health#islands
