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

🚀 Energy Giants Face Challenges Amid Rising Oil and Gas Prices Due to Iran Conflict Rising oil and gas prices resulting from the ongoing conflict in Iran might initially appear beneficial for energy companies. Bloomberg posted on X, however, that the situation is more complex due to supply disruptions, shipping blockades, and hedging losses. These factors are creating a challenging environment for energy giants, impacting their ability to capitalize on the price surge. The conflict has led to significant disruptions in the supply chain, affecting the transportation and availability of oil and gas. Additionally, shipping blockades are further complicating the situation, making it difficult for companies to maintain steady operations. Hedging losses are also a concern, as companies that had previously locked in prices at lower rates are now facing financial setbacks. As the situation unfolds, energy companies are navigating a complex landscape, balancing the potential benefits of higher prices with the operational challenges posed by the conflict. #EnergyGiants#OilPrices#GasPrices#IranConflict#SupplyDisruptions#ShippingBlockades#HedgingLosses#EnergyCompanies#FinancialSetbacks#OperationalChallenges
