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😉

#Commentary: #Oromia’s New Regulation: Legalizing construction on illegally possessed land, enabling geography-based discrimination
Oromia’s Regulation No. 259/2026 (March 2026) legalizes illegally built properties—yet excludes #Shaggar, #Adama, and #Bishoftu. Hassen Mama Muse argues, "This geographic exclusion creates a two-tiered system, violating constitutional equality."
The law covers construction projects from 2013 to 2026 that meet the criteria but excludes some residents from facing demolition. This contradicts Article 25 of #Ethiopia’s Constitution and treaties like the #ICCPR. The regulation also fails Lon Fuller’s "internal morality of law" and exceeds the Council’s authority under Proclamation No. 242/2021.
According to the author, urgent reforms are needed: include all cities, compensate evictees, and review constitutionality." A fair framework must protect all equally," he emphasizes, "or entrench inequality as reform."

News: EPRP calls for nationwide protest on May 8 amid concerns over electoral conditions
The Ethiopian People’s Revolutionary Party (#EPRP) has called for a nationwide peaceful protest to be held on May 8, 2026, citing what it described as the absence of “enabling conditions” for a credible election in #Ethiopia.
In a statement sent to Addis Standard today, the party said the planned demonstrations will take place in several major cities, including #Addis_Abeba, #Mekelle, #Bahir_Dar, #Gondar, #Hawassa, #Adama, and #Ambo, urging #Ethiopians to join what it described as a peaceful effort to demand political reforms.
The EPRP said it supports the transfer of power through elections but argued that current conditions do not allow for a “free, fair, and credible” vote. It accused the ruling Prosperity Party of attempting to conduct what it termed a “pseudo-election” aimed at extending its hold on power, describing the process as
