## **FastAPI**-Kompatibilität { #fastapi-compatibility }

Die Einfachheit des Dependency Injection Systems macht **FastAPI** kompatibel mit:

* allen relationalen Datenbanken
* NoSQL-Datenbanken
* externen Packages
* externen APIs

	WrittenByVersion uint64                `msg:"v"` // Tracks written by MinIO version
}

// xlFlags contains flags on the object.
// This can be extended up to 64 bits without breaking compatibility.
type xlFlags uint8

const (
	xlFlagFreeVersion xlFlags = 1 << iota
	xlFlagUsesDataDir
	xlFlagInlineData
)

func (x xlFlags) String() string {
	var s strings.Builder

### Deprecation

    public boolean removeAll(Collection<?> c) {
      return removeAllImpl(this, c);
    }

    @Override
    public boolean retainAll(Collection<?> c) {
      return super.retainAll(checkNotNull(c)); // GWT compatibility
    }
  }

  /**
   * Returns an immutable set instance containing the given enum elements. Internally, the returned
   * set will be backed by an {@link EnumSet}.
   *

그리고 "말 그대로", 그저 필요로 하는 파이썬 패키지를 임포트하고 단 몇 줄의 코드로 여러분의 API 함수와 통합함으로써, 의존성을 아주 간단하고 직관적인 방법으로 만들 수 있습니다.

관계형 및 NoSQL 데이터베이스, 보안 등, 이에 대한 예시를 다음 장에서 볼 수 있습니다.

## **FastAPI** 호환성 { #fastapi-compatibility }

의존성 주입 시스템의 단순함은 **FastAPI**를 다음과 같은 요소들과 호환할 수 있게 합니다:

* 모든 관계형 데이터베이스
* NoSQL 데이터베이스
* 외부 패키지
* 외부 API
* 인증 및 권한 부여 시스템
* API 사용 모니터링 시스템
* 응답 데이터 주입 시스템
* 기타 등등.

### Other notable changes

* Kubernetes json deserializer is now case-sensitive to restore compatibility with pre-1.8 servers. ([#65157](https://github.com/kubernetes/kubernetes/pull/65157), [@caesarxuchao](https://github.com/caesarxuchao))
    * If your config files contains fields with wrong case, the config files will be now invalid.

the DockerValidor and ServiceCheck for the `docker` service from kubeadm preflight. Docker is no longer special cased during host validation and ideally this task should be done in the now external cri-dockerd project where the importance of the compatibility matters. Use `crictl` for all communication with CRI sockets for actions like pulling images and obtaining a list of running containers instead of using the docker CLI in the case of Docker.
