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😉

🇮🇳🤝🇷🇺 Strengthening India–Russia Trade
On August 18, we hosted a business meeting at the Moscow Chamber of Commerce and Industry with the FICCI delegation.
✔ Bilateral trade has reached $67B — discussions at Innoprom 2025 aim to expand it to $100B.
✔ Opportunities for India in energy, manufacturing, agriculture, and textiles.
✔ Addressing the trade imbalance and exploring a Rouble–Rupee exchange mechanism.
Recently, I shared India’s perspective on RBK TV after the US imposed a 25% duty on Indian goods:
> “India, as the world’s 4th largest economy, has the right to protect its strategic sovereignty.”
A strong Indian business presence in Moscow reflects our shared commitment to deeper economic cooperation.
