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😉

The last time we met
The last words you Said
were not just words ,
But bullets in my lungs .
These beautiful clouds and cold Wheather ,
Reminds me of the moments we spent together .
Celebrating first Eid in your absence ,
Makes me guilty for my existence.
Scrolling through my WhatsApp
these days,
feels that life has left me no ways
I always felt happy whenever we met ,
But now ,
Your name forces me to regret ,
Your wait compels me to forget ,
And , even your thoughts pierces my heart.

It was 3am back then
I was laying on the bed
The Mullioned windows were open
The stars above in the night were gleaming
Suddenly onshore breeze had started
I turned off my phone and Started
Thinking of a dazzling Lady
I was devising a Scenario
of me and the graceful Lady
The scenario doesn't exist in real
But,
it gives peace In real
It gives me the Inner endearments
It gives a feeling that is forthcoming
I was fully Shifted to palace with her
That place was completely Magical
We were creating an album of Our life
And in an instant, it started Thundering
I Woke up from my pleasant Dream
The high wind started, The birds were
Moving from one tree to another
I closed my Windows
Gradually Heavy Downpour started
The Dream was left incomplete
But I made a Smile
And Thanked that period
For making me contented in
Today's Selfish World.

...Boshqa ilovalarga oʻtishni hojati yoʻq. Boshqa dasturlarni mazasini qochiramiz! 😎 (deyaptilar, menimcha aka)

🟢Paynet uchun elektr limitini funksiyasini qo'shish uchun taklif dizayn
— Shunchaki, Paynetdan foydalanganim uchun taklif sifatida chizdim)
P.s. Dizayn paynet dasturining dizayn tizimiga asoslangan holda chizilgan. UI'dagi kamchiliklar ustida detalniy to'xtalmaganman.
