**FastAPI**를 사용하면 여러분은 **Starlette**의 기능 대부분을 얻게 될 것입니다(FastAPI가 단순히 Starlette를 강화했기 때문입니다):

* 아주 인상적인 성능. 이는 <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">**NodeJS**와 **Go**와 동등하게 사용 가능한 가장 빠른 파이썬 프레임워크 중 하나입니다</a>.
* **WebSocket** 지원.
* 프로세스 내의 백그라운드 작업.
* 시작과 종료 이벤트.
* HTTPX 기반 테스트 클라이언트.
* **CORS**, GZip, 정적 파일, 스트리밍 응답.

         * to support DFS referral _to_ Win95/98/ME.

writing data to the datastore. Object storage operations are atomic by nature and they do not require/implement rename API. The default S3A committer emulates renames through copy and delete APIs. This interaction pattern causes significant loss of performance because of the write amplification. _Netflix_, for example, developed two new staging committers - the Directory staging committer and the Partitioned staging committer - to take full advantage of native object storage operations. These committers...
