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😉

EVAA Protocol: Temporary Suspension of stTON in Main Pool
#protocol#liquidity
EVAA has temporarily suspended the use of stTON as collateral in its Main Pool due to reduced market liquidity. Existing positions remain unaffected, but users must repay active loans before withdrawing stTON. The measure is temporary and will be lifted once liquidity conditions improve.

🚀 StarkWare Researcher Proposes Complex Bitcoin Transaction Scheme
StarkWare researcher Avihu Mordechai Levy has introduced a Bitcoin transaction scheme that aims to circumvent the need for a protocol change. According to NS3.AI, the proposed method involves solving a pre-broadcast puzzle, which would necessitate approximately 70 trillion attempts. Levy characterized this design as a last-resort solution due to its significant computational demands, large transaction size, and potential relay-policy challenges, all of which could hinder scalability.

Ethereum Rollback Not Feasible, Developer Warns
Ethereum developer Tim Beiko cautions against rolling back the Bybit attack, citing potential widespread disruptions and significant costs exceeding $1.5 billion. This attack does not breach Ethereum protocol rules unlike the 2016 TheDAO incident. Additionally, a Bybit address transferred $48 million to Galaxy Digital and FalconX, acquiring 34,800 ETH shortly before depositing it back into Bybit.

🚀 Polymarket to Upgrade Protocol and Launch pUSD Token on Polygon
Polymarket has announced plans to enhance its protocol and introduce pUSD, an ERC-20 collateral token on the Polygon network, fully backed by USDC. According to NS3.AI, the upgrade aims to lower gas costs and minimize failed trades. The platform intends to open-source the smart contracts next week and will initiate a bug bounty program to ensure security and reliability.

Geyser is a free tool that lets you play Minecraft across different versions by connecting Minecraft Java Edition servers. It works by translating data between the two game versions, enabling cross-platform play on devices like Windows, iOS, Android, and consoles. You can install it as a plugin or standalone, and it supports recent Minecraft versions. This means you can join Java servers even if you only have Bedrock Edition, expanding your multiplayer options without needing a separate Java account if you use the Floodgate plugin. It’s great for seamless crossplay but may have some minor limitations due to game differences[1][2][5].
