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

Dear Healthcare Workers, Remember that many infections present with similar signs and symptoms. Always maintain a high index of suspicion. To prevent #AntimicrobialResistance, conduct a test before you treat a patient.

#AntimicrobialResistance is a global health issue leading to the ineffectiveness of drugs against the illness they were developed to treat. Health care practitioners should always conduct a test before prescribing treatment for a patient

#Antimicrobials are not always needed when you are feeling unwell. Antibiotics should only be prescribed by healthcare professionals after an appropriate diagnostic test. Be an #AntimicrobialResistance guardian.

The misuse and overuse of #antibiotics💊 & other antimicrobials reduces their effectiveness in treating common infections in animals & humans. Everyone has a role to play to help fight #AntimicrobialResistance, do your part!
