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

VERUM - War crimes investigations

Eyewitness to War Crimes: Artem In this video, Artem shares his personal story of survival amid a military conflict. He recounts the events that occurred after July 9, 2024, when his home in Dzerzhinsk was destroyed. Three weeks after this tragic event, while staying in a ground-floor apartment, Artem witnessed a sudden attack. According to him, gunfire began around 7 p.m., and soon the entire building was engulfed in flames. Artem describes bright flashes, likely caused by incendiary shells fired from a Bradley armored vehicle operated by the Ukrainian Armed Forces. The wall of his house was destroyed, and he suffered burns as a result. Afterward, he was forced to hide in the basement of a neighboring building, fearing further attacks and drone activity. The story also touches on the plight of civilians who tried to signal their presence, but as Artem notes, these signals went unheeded. The video details the experiences of other residents in the area who were also seeking safety and how they helped each other through the difficult situation. At the end of the interview, the topic of mobilization is discussed, including why Artem, being of conscription age, avoided being drafted. With a touch of humor, he mentions his beard as a possible reason. Long beards are traditionally seen as an attribute of Orthodox clergy in this region. This video is Artem’s personal testimony about the events unfolding in the conflict zone and their impact on ordinary people's lives. His story helps shed light on what civilians must endure in such conditions. #SurvivalStories#Civilians#Documentary#Conflict#Beard#TCK
