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😉

🚀 U.S. March CPI Rises Sharply Amid Conflict with Iran
The U.S. Consumer Price Index (CPI) for March showed a significant increase, driven by soaring gasoline prices due to the ongoing conflict with Iran. According to Jin10, the seasonally adjusted CPI rose by 0.9% month-on-month, marking the largest increase since 2022. Data released on Friday indicated that the CPI climbed 0.9% from February, with the year-on-year growth rate accelerating to 3.3%, the fastest pace since 2024. The U.S. Bureau of Labor Statistics noted that the record surge in gasoline prices contributed nearly three-quarters of the monthly CPI increase. Meanwhile, the core CPI, which excludes food and energy costs, saw a more modest rise of 0.2% month-on-month.

🚀 Investors May Shift Focus from Geopolitical News to Economic Data, Analyst Suggests
On April 13, Christian Gattiker, Head of Research at Bank Julius Baer, indicated in a research report that investors might be becoming less sensitive to daily Middle Eastern headlines. According to Jin10, Gattiker noted that after weeks of geopolitical dominance in the markets, there is a significant possibility that investors will cautiously return to a more 'normal' market mechanism, focusing on macroeconomic data and corporate fundamentals. Upcoming U.S. producer price data, industrial output figures, and the Federal Reserve's Beige Book are expected to provide insights into inflation dynamics and potential economic momentum.

🚀 U.S. CPI Watch: U.S. CPI Jumps 0.9% in March, Highest Since 2022 as Oil Drives Inflation Surge
Key TakeawaysU.S. CPI rose 0.9% MoM, largest increase since 2022.Inflation hit 3.3% YoY, fastest pace since 2024.Gasoline accounted for ~75% of the monthly increase.Core CPI (ex-food & energy) slowed to 0.2% MoM.Inflation Surges on Energy ShockLatest data from the U.S. Bureau of Labor Statistics shows a sharp acceleration in inflation for March, with headline CPI rising 0.9% month-on-month.This marks the largest monthly increase since 2022, highlighting the growing impact of energy prices on the broader economy.Gasoline Prices Drive Majority of IncreaseThe surge in inflation was overwhelmingly driven by rising fuel costs linked to geopolitical tensions.Key detail:Gasoline contributed nearly three-quarters (~75%) of the CPI increaseThe spike reflects the ripple effects of higher oil prices amid the Iran conflict, which has tightened global energy supply.Yearly Inflation Accelerates to 3.3%On a yearly basis:CPI rose 3.3% YoY, the fastest pace since 2024This suggests inflation pressures are re-accelerating after a period of relative stabilization.Core Inflation Shows Signs of CoolingDespite the headline surge, underlying inflation remains more contained:Core CPI (excluding food and energy): +0.2% MoMThis indicates that:Price pressures are still largely energy-drivenBroader inflation may not yet be fully entrenchedMarket ImplicationsThe data presents a mixed signal for markets:Bullish for rates / USD:Strong headline inflationReinforces “higher-for-longer” Fed stanceNeutral-to-positive for risk assets (conditionally):Core inflation remains controlledSuggests inflation spike may be temporary if energy stabilizesEnergy vs Core Inflation BattleThe key question going forward is whether energy-driven inflation spills into the broader economy.Markets will closely watch:Wage growth trendsCore inflation trajectoryOil price stabilityIf energy pressures persist, inflation could remain elevated. If not, the spike may prove temporary.For now, the data reinforces a macro environment of elevated uncertainty, with inflation increasingly tied to geopolitical developments.
