### Bug or Regression

- Fix a scheduler preemption issue where the victim pod was not deleted due to incorrect status patching. This issue occurred when the preemptor and victim pods had different QoS classes in their status, causing the preemption to fail entirely. ([#126694](https://github.com/kubernetes/kubernetes/pull/126694), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling]

  as deprecated and print a warning if it is used directly; it will be removed in
  a future release. Add a replacement sub-phase ''enable-client-cert-rotation''.' ([#124419](https://github.com/kubernetes/kubernetes/pull/124419), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

Das sollte jetzt mehr Sinn ergeben. ✨

All das ist es, was FastAPI (via Starlette) befeuert und es eine so beeindruckende Performanz haben lässt.

Dies sind sehr technische Details darüber, wie **FastAPI** unter der Haube funktioniert.

- Fixes a regression in kube-apiserver causing 500 errors from the `/readyz` endpoint ([#93645](https://github.com/kubernetes/kubernetes/pull/93645), [@ialidzhikov](https://github.com/ialidzhikov)) [SIG API Machinery]

### Other (Cleanup or Flake)

> 최신 파이썬 버전은 **`async` 및 `await`** 문법과 함께 **“코루틴”**이라고 하는 것을 사용하는 **“비동기 코드”**를 지원합니다.

이제 이 말을 조금 더 이해할 수 있을 것입니다. ✨

이것이 (Starlette을 통해) FastAPI를 강하게 하면서 그것이 인상적인 성능을 낼 수 있게 합니다.

## 매우 세부적인 기술적 사항

/// warning | "경고"

이 부분은 넘어가도 됩니다.

이것들은 **FastAPI**가 내부적으로 어떻게 동작하는지에 대한 매우 세부적인 기술사항입니다.

만약 기술적 지식(코루틴, 스레드, 블록킹 등)이 있고 FastAPI가 어떻게 `async def` vs `def`를 다루는지 궁금하다면, 계속하십시오.
