Issue
✨ 구현한 기능
오늘 아침에 다같이 논의했던대로
Product 엔티티에 reviewCount 필드 추가 (반정규화) 진행했습니다.
📢 논의하고 싶은 내용
🎸 기타
사용자가 서비스 접속시 가장 많이 접근하는 페이지는 홈과 상품 목록 페이지이다.
그 중 상품 목록 페이지의 경우 상품에 대한 정보와 리뷰의 개수를 함께 보여준다.
(기존)
상품 목록 조회시 상품과 리뷰를 JOIN * 10번
(반정규화시)
상품 목록 조회시 상품 단독 조회 * 10번
리뷰를 작성하는 것보다 (reviewCount++) 상품 목록 조회(join)가 더 자주 발생할 것이라 판단하여 반정규화를 진행한다.
