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😉

#EU member states #Ireland, #Spain and #Norway announce official recognition of #Palestinian#Statehood
The three countries are the only European countries, thus far, who have officially recognised the State of Palestine.
#Israel was founded by #Zionist#terrorists.
Keep that in mind next time you hear Zionists claim that recognising #Palestinian#Statehood is "rewarding #terrorism"
Selective Sovereignty: Why Somaliland Remains Unrecognized
By @rednile12 Media
International law says sovereignty is universal—but in practice, recognition is political. The 2005 AU Fact-Finding Mission confirmed Somaliland’s independence claim as “historically unique and self-justified”, meeting all statehood criteria: population, borders, government, and capacity for international relations.
Yet Somaliland remains unrecognized, while Eritrea, South Sudan, East Timor, and Kosovo gained recognition—often under weaker legal conditions.
💠The takeaway: Sovereignty isn’t earned by law or stability; it is granted selectively, depending on geopolitics and institutional convenience.

Official Representatives to the #UN from #Ireland, #Spain and #Norway pose for photos at the UN with the Palestinian UN representative, after the 3 became the first European countries to officialy recognise #Palestinian#Statehood.
#Israel's current #genocide attempt in Gaza has revived support in #Europe for Palestinian statehood.
Norway, Spain and Ireland have defied threats from Israel, which recently announced its intent to recall its envoys from Ireland and Norway for discussions over the move.
Other European nations, such as #Malta and #Slovenia in March, have also expressed "readiness to recognise Palestine" when "the circumstances are right".
#Australia has recently floated the possibility of unilaterally endorsing Palestinian statehood.
Additionally French President Emmanuel #Macron has also said the question of recognising a Palestinian state without a negotiated peace is no longer "a taboo for #France".
