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😉

We have completed the first series of posts, where we showed the interface of the future BLC Market application.
What's next.
The project is now moving into the next phase:
• interface testing within the Pioneers group
• feedback collection
• preparation of the backend part of the application
• development of the referral system and game mechanics
Also in development is the first game mechanic of the application - the tap module.
It will become part of the BLC economic system.
The next updates will be dedicated to:
• application testing
• referral mechanics
• early participant system
The development of the project continues.

We continue to show what the BLC Market will look like.
Currently, the basic logic of interaction within the app is under development:
— user profile
— task structure
— navigation within the interface
This is the first layer on which the entire system will be built.
Next, we will show how exactly users will interact with each other.

How interaction will work in BLC Market
The main idea is to eliminate unnecessary intermediaries.
User:
- creates a task
- receives responses
- chooses a contractor
Everything happens within one interface.
We make the mechanics as simple as possible to lower the entry barrier.

Why do we emphasize on interface?
Most Web3 products are complex.
We are going in a different direction:
— simple structure
— clear actions
— minimum of unnecessary steps
Convenience first, then everything else.
This is critical for mass use.
