# 베타 및 실험적 기능

> ClickHouse에는 베타 및 실험적 기능이 있습니다. 이 문서에서는 그 정의를 설명합니다.

ClickHouse는 오픈소스이므로 ClickHouse 직원뿐 아니라 커뮤니티에서도 많은 기여가 이루어집니다. 이러한 기여는 개발 속도가 제각각인 경우가 많으며, 일부 기능은 일반 제공(GA)으로 간주되기까지 긴 프로토타이핑 단계가 필요하거나 충분한 커뮤니티 피드백과 반복 개선을 위해 더 많은 시간이 필요할 수 있습니다.

기능이 언제 일반 제공으로 분류될지 불확실할 수 있으므로, ClickHouse에서는 기능을 **베타**, **실험적**, **비공개 프리뷰**의 세 가지 범주로 구분합니다.

**베타** 기능은 ClickHouse 팀이 공식적으로 지원합니다. **실험적** 기능은 ClickHouse 팀 또는 커뮤니티가 주도하는 초기 프로토타입이며, 공식적으로 지원되지 않습니다. **비공개 프리뷰** 기능은 일반 제공으로 나아가는 명확한 경로에 있지만 아직 적용 범위가 제한적이며 프로덕션 환경에서의 사용은 권장되지 않습니다.

아래 섹션에서는 **베타**, **실험적**, **비공개 프리뷰** 기능의 특성을 명확히 설명합니다.

<h2 id="beta-features">
  베타 기능
</h2>

* 일반 제공(GA)을 목표로 활발하게 개발 중입니다
* 알려진 주요 문제는 GitHub에서 추적할 수 있습니다
* 향후 동작이 변경될 수 있습니다
* ClickHouse Cloud에서 활성화될 수 있습니다
* ClickHouse 팀에서 베타 기능을 지원합니다

아래에서 ClickHouse Cloud에서 베타로 간주되며 ClickHouse Cloud 서비스에서 사용할 수 있는 기능을 확인할 수 있습니다.

참고: 최근 도입된 기능을 사용하려면 ClickHouse [compatibility](/ko/reference/settings/session-settings/compatibility#compatibility) 설정의 최신 버전을 사용하고 있는지 확인하십시오.

<h2 id="experimental-features">
  실험적 기능
</h2>

* 일반 제공(GA)되지 않을 수 있습니다
* 제거될 수 있습니다
* 호환성이 깨지는 변경이 발생할 수 있습니다
* 기능의 동작이 변경될 수 있습니다
* 명시적으로 활성화해야 합니다
* ClickHouse 팀은 실험적 기능을 **지원하지 않습니다**
* 중요한 기능과 문서가 부족할 수 있습니다
* ClickHouse Cloud에서는 활성화할 수 없습니다

참고: 위에 베타로 나열된 항목 외의 추가 실험적 기능은 ClickHouse Cloud에서 활성화할 수 없습니다.

<h2 id="private-preview-features">
  비공개 프리뷰 기능
</h2>

* 일반 제공(GA)을 향한 명확한 로드맵이 있습니다
* 적용 범위가 아직 제한적입니다
* 프로덕션 사용에는 권장되지 않습니다
* 기능의 동작이 향후 변경될 수 있습니다
* 명시적으로 활성화해야 합니다
