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

Rabbits can see behind themselves without moving their heads due to their laterally placed eyes. Their only, small blind spot is directly in front of their nose. @googlefactss#animals

The scientific name for "coyote" is canis latrans, which literally means "barking dog", a fitting description for its wide variety of yips, howls, and barks used for communication, with the name coming from the Aztec word for the animal. @googlefactss#animals

Female elephants stay with the same herd their entire lives. Males only remain with the herd until they are 12 to 15 years old. The Male elephants then either join a "bachelor" herd or they live alone only rejoining the females during mating season. @googlefactss#animals

#Animals Animals help each other too, and sometimes they do it more sincerely than humans. In nature, there are many amazing examples of cooperation: birds warn their flock about danger, dolphins support injured companions, elephants protect their calves, and some animals share food with those who are weak. This invisible bond of support and care is part of the harmony of nature. In the wild, survival often depends on cooperation and strong social connections. By observing animals, we learn a simple truth: the world is sustained not only by strength, but also by compassion, trust, and mutual help. 🐾🌿☘️Read the latest environmental news on the @ekologuz page.
