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

Franklin D. Roosevelt was the 32nd U.S. President. He led the country through the Great Depression by creating jobs and helping people with new programs. He also guided the U.S. during World War II. FDR was the only president elected four times—last elected on November 7, 1944, and started his fourth term on January 20, 1945. After his presidency, the 22nd Amendment was passed, limiting presidents to two terms. 🇺🇸🗳️ [Read more] @googlefactss #FDR#USPresident#History#GreatDepression#WWII#22ndAmendment

🚀 Strait of Hormuz Traffic Halts Following U.S. Maritime Blockade All maritime traffic through the Strait of Hormuz has reportedly ceased after U.S. President Donald Trump declared a maritime blockade via social media. According to NS3.AI, information from British sources, as reported by CCTV News, indicated that the blockade had been in place for several hours. While traffic was still feasible on the 12th, at least two vessels attempting to exit the strait reversed course. Tanker traffic had seen a slight uptick on the 11th before declining on the 12th. #StraitOfHormuz#MaritimeBlockade#USPresident#DonaldTrump#TankerTraffic#CCTVNews#NS3AI#MaritimeTraffic

🚀 Trump Highlights Incoming Oil Tankers to the U.S. On April 11, U.S. President Donald Trump announced on his Truth platform that numerous empty oil tankers, including some of the world's largest, are currently en route to the United States. According to BlockBeats, these tankers are carrying some of the highest quality oil and natural gas globally. Trump emphasized that the U.S. oil reserves surpass the combined reserves of the second and third largest oil-producing countries, both in quantity and quality. He invited attention to this development, urging prompt action. #Trump#OilTankers#USOilReserves#NaturalGas#Energy#GlobalOil#TrumpAnnouncement#USPresident#BlockBeats
