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

🚀 Binance to Enhance VIP Loan Services with New Fixed Rate Options According to the announcement from Binance, the platform is set to enhance its VIP Loan services starting from 2026-04-09 08:00 (UTC). This update will allow users to borrow Fixed Rate Loan orders directly from the VIP Loan page, offering a more seamless borrowing experience. The new feature aims to provide users with additional fixed rate options while benefiting from an extensive list of collateral assets available under the VIP Loan program. The key updates include the introduction of additional liquidity from Fixed Rate Loans. Users will now have the ability to borrow Fixed Rate Loan orders directly from the VIP Loan page, in addition to the standard VIP Loan fixed rates. This update also introduces streamlined batch borrowing, enabling users to borrow multiple Fixed Rate Loan orders in one batch. Furthermore, the service will support multi-collateral pledging, allowing users to use multiple asset types as collateral for a single loan. This offers a wider range of eligible collateral compared to standard Fixed Rate Loans. Additionally, the update provides flexibility at maturity. When the loan term ends, users can choose to auto-repay, repay early, or convert to a Flexible Rate loan to continue borrowing seamlessly. Binance VIP Loan is designed as a large personal and institutional over-collateralized loan service, offering competitive rates, terms, and services. It aims to unlock greater potential for users in objectives such as increased liquidity for long-term investment funds, leveraged trading, and hedging strategies. Users are advised to monitor their loan-to-value (LTV) ratios closely to avoid potential liquidations or losses due to changes in collateral ratios. Binance emphasizes that it is not responsible for any losses incurred if users fail to adjust their collateral while using Binance Loans products. #Binance#VIPLoan#FixedRateLoan#CollateralAssets#BatchBorrowing#MultiCollateral#LoanRepayment#Liquidity#LeveragedTrading#HedgingStrategies#LTVRatio#CryptoLoans
