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

人類研究幾千年來 大部份人也是基因混血 國家/國籍 = 與基因血緣沒有關係 基因= 大部份人的基因也沒有100%純正 歷代祖先 = 很多今天的國家,在古代也不存在, 所以不要亂說自己祖先是那國及那種人。 膚色 = 人種頂多能分 : 黑人 白人 黄人 及中亞人 , 再細分也是一樣, 某國那國也只是國籍政治及文化圈劃分( 基因也是不純的) #Human

In 1978, Richard Branson wanted to impress his girlfriend by pretending to buy a private island. The island was listed for $6 million and he offered $100,000 as a joke. The owner settled for $180,000 and Branson bought Necker Island. #Human 🔔@Everything_Science
