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

🚗💨 Exciting news from Lamborghini! The upcoming Lamborghini Temerario is set to unleash over 1000 horsepower! 🔥 Ruwen Mor, a former Audi engineer now at Lamborghini, revealed that the power of the V8 engine could increase from 200 to around 220 hp per liter. Plus, the car will feature three electric motors for an extra boost! ⚡️ The Temerario follows in the footsteps of the iconic Huracan, which had a naturally aspirated V10 engine with a peak output of 640 hp. While a V6 could have delivered even more power, the decision was made to stick with a higher cylinder count to meet customer expectations. 💪 #Lamborghini#Temerario#Supercar#1000HP#V8#ElectricPower#CarEnthusiast#LuxuryCars#Auto

🚀 France Shifts Focus to Electric Power Amid Rising Oil Prices French Prime Minister Sebastien Lecornu announced a strategic shift in government policy, emphasizing investment in electric power over short-term fuel aid. Bloomberg posted on X that this decision comes in response to the recent surge in oil prices triggered by the conflict in Iran. Lecornu highlighted the importance of supporting households and businesses in transitioning to electric power as a sustainable solution to the energy crisis. The government aims to reduce dependency on fossil fuels and promote cleaner energy alternatives. This move is part of a broader effort to address the economic impact of rising oil prices and ensure long-term energy security for the nation. #France#ElectricPower#OilPrices#EnergyTransition#RenewableEnergy#EnergyPolicy#SustainableEnergy#FossilFuelReduction#EnergySecurity#EconomicImpact
