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😉

When Africa Said No: Zimbabwe and Zambia Reject the “America First” Health Strategy — And Why Ethiopia’s History with U.S. Aid Made It Blind
By Alexander Yohannes | On Medium
Early February 2026: two African nations did what once seemed unthinkable.
First Zambia. Then Zimbabwe.
Both rejected major U.S. health aid packages—not because they didn’t need funding, but because the cost was sovereignty. The agreements reportedly included long-term access to strategic data and biological resources under Washington’s “America First” framework.
These were not quiet diplomatic gestures. They were public, strategic refusals.
For Ethiopia, however, the moment raises an uncomfortable question.
On December 23, 2025, Addis Ababa signed a $1.466 billion agreement under the same strategy. Why did others walk away while Ethiopia said yes?
The answer lies deep in our modern history—Cold War alignment, famine-era dependency, structural adjustment, and decades of institutional reliance on U.S. aid. Over time, survival partnerships can reshape national instincts.
Sovereignty begins to feel negotiable when funding gaps feel existential.
Zambia and Zimbabwe drew a line.
Did Ethiopia?
