차량 대절 쿼리 성능 개선

구현 내용 📢

1. 역정규화 진행

차량 대절 신청 인원에 대해 역정규화를 진행했습니다.
더이상 RentJoin을 SUM(passenger_num)할 필요 없이, 바로 RentBoardingInfo 테이블에서 passenger_count를 조회하면 됩니다.

2. 테이블 이름 수정

• rent_form -> rent
• rent_form_boarding_date -> rent_boarding_info
• rent_join -> 그대로

3. 쿼리 개선

rent와 rent_boarding_info, rent_join인 간 JOIN 하는 과정에서 병목 현상을 발견했습니다.
이에 제대로 식별자를 통해 구분할 수 있도록 JOIN 조건 절을 수정했습니다.

4. 인덱스 추가

• rent_join member_id 인덱스 추가
• rent_boarding_info (rent_id, date) 인덱스 추가

성능 개선을 통해 100만개 테스트 데이터 기준, 1분 이상 걸리던 조회가 약 200ms로 줄었습니다~

테스트 결과 🧩

정상 동작합니다~

리뷰 포인트 📌

• 쿼리 변경
• 인덱스
• 컬럼 수정 및 테이블명 수정으로 인한 side effect 가능성

• [nitpick] Consider renaming 'rentBoardingDateRequests' to 'rentBoardingInfoRequests' for consistency with the updated domain model.

List<RentBoardingInfo> rentBoardingInfos = rentBoardingDateRequests.stream()
