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

⚠️ AIR POLLUTION IS A SERIOUS CONCERN! In Quvasoy city, Do‘stlik residential area, the 82-KMK reinforced concrete products manufacturing plant is releasing toxic gases and other harmful substances into the atmosphere on a daily basis. This situation poses a real threat to public health and the environment. Under the current circumstances, a legitimate question arises: ❓ How lawful and acceptable is such activity today? We, as members of the public, respectfully but firmly request: 🔹 a thorough investigation of these emissions, 🔹 verification of whether the enterprise operates in full compliance with environmental and sanitary legislation, 🔹 and the adoption of appropriate measures if violations are identified. 🟢 Clean air is not a privilege — it is a fundamental right of every citizen. 🟢 Public health must take precedence over industrial interests. Responsible authorities should not remain indifferent. The public will continue to monitor this situation closely. #AirPollution #Quvasoy #Dostlik #Environment #PublicHealth #EnvironmentalProtection☘️Read the latest environmental news on the @ekologuz page.

Fergana Region, Fergana District, Mindonobod Neighborhood: We can’t breathe, please help! Our homes are located near an asphalt plant, and due to its operations, dust and emissions enter our homes every day. If you step outside around 5–6 a.m., you can see the air is covered in haze. This situation seriously affects the health of our children: allergies and respiratory problems are increasing. We have repeatedly submitted complaints through the clinic, neighbors, and other organizations, and sent letters to higher authorities, but no measures have been taken. The environmental agency has also failed to address the problem. In addition, next to the asphalt plant, there are Megamix and Alibaster production facilities, whose emissions further worsen the air quality. We are calling on the public and responsible authorities: please pay attention to this air pollution and the threat it poses to our children’s health, and take the necessary measures! #Fergana#Mindonobod#Environment#AirPollution#ChildHealth#AsphaltPlant ☘️ Follow the latest environmental news on @ekologuz.
