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

🚨 Urgent Call for Ceasefire in Gaza 🚨 USAID staff demand immediate end to violence, decrying civilian deaths and violations of international law. Aid efforts futile amidst indiscriminate bombing. Gaza needs more than just aid, it needs the bombs to stop. Pressure mounts on US government to take action, hold all parties accountable. UN warns of grave risk of genocide. Meanwhile, US continues unwavering support for Israel, providing billions in military aid. Will Congress break the silence? #CeasefireNow#GazaCrisis https://www.aljazeera.com/news/2023/11/8/more-than-1000-usaid-employees-sign-letter-backing-gaza-ceasefire Subscribe to @BadVolfNews

UN chief warns of "immense suffering" as Gaza aid remains inadequate. Israel's relentless bombardment overwhelms hospitals and leaves Gaza without essential supplies. More than 8,500 lives, including children, have been lost. The situation is "absolutely horrific", says Red Crescent. Calls for a ceasefire and increased humanitarian aid are rejected by the US, prioritizing their support for Israel. As the death toll rises, the UN pleads for an end to this "spiral of death". The world must act now to prevent further tragedy. #GazaCrisis#HumanitarianAid https://www.aljazeera.com/news/2023/10/31/un-chief-guterres-says-aid-trickling-into-gaza-is-completely Subscribe to @BadVolfNews
