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

Pump Leaks

@pumpleaks · Post #678 · 06.01.2024 г., 00:36

Pump Result: One of the best pumps we’ve had. The volume crossed an unprecedented $3.2 million in the first 15 minutes, catapulting #LAYER to our 10x target (957%) and making all of our members huge profits, that’s exactly why we’re the best in the world. Our coin held as the top gainers for hours after our signal, demonstrating the real power of our whales and market makers. Even though we saw a huge volume of external selling (very likely coming from the coin team), we truly delivered on the expected exceptional first pump of the year, and things are just going to get better from here. We’re still receiving an overwhelming amount of gratitude messages from members that scored big, and asking for our next pump. No stress, enjoy the profits, we’ll announce it soon. In the meantime, we’re focusing our efforts on never used before marketing strategies to bring in over 1 million new members for our next Kucoin Mega Pump, which will absolutely dwarf anything we’ve seen until now. Stay tuned for our next pump announcement.
