  • Post 수정에서 Category 변경 가능
  • 카테고리 생성 /new-category
  • 카테고리 수정 /category/{id}/edit

[Alpha v0.0.7 → vX.X.X] 성능 테스트

성능 테스트 진행

  • 어느정도 트래픽까지 감당가능한가? (스트레스테스트 목표 설정하기)
  • 부하는 발생하지 않는가? (부하테스트 목표 설정하기 - 동접 500명?)

[Alpha v0.0.5] 썸네일 이미지 S3, CDN 적용하기

게시글 이미지 CDN 적용하기

현재로서는 S3 + Cloudflare CDN이 최선이다. 그런데 나중가면 인피니트 스크롤링 뷰라 S3 프리티어 한도 초과할 가능성있음. R2 나오면 바로 이주하자.

스토리지

  1. AWS S3
  2. Cloudflare R2

https://youtu.be/-AwLsUuzgLw

S3

  • 프리티어 매달 5GB 스토리지, 20,000건 GET, 2,000 PUT, COPY, POST, LIST 요청까지
  • 1GB당 월 0.025$, 데이터 전송 GB당 0.126$ (참고)

R2 사용하고 싶은데 아직 베타 오픈을 안헀다.


CDN

  1. AWS CloudFront
  2. Cloudflare CDN

Cloudfront

  • 매달 1TB 데이터 전송, 천만건 요청, 2백만건 함수 호출 무료 (참고)

Cloudflare CDN

  • 프리이터 무제한 대역폭 비용 무료

Likes 구현 (Member -Post의 중간 테이블)

Mebmer - 1 : N - Likes - N : 1 - Post 구현

  • Likes -> Member 멤버 id를 저장한다 (단방향)
  • Likes -> Post 게시글 id를 저장한다. / Post -> Likes 멤버가 좋아요 누른 게시글 조회 (양방향)
    • select ~ from Post join Like where Like.memberId

좋아요 추가하기 /like/add
좋아요 삭제하기 /like/remove
멤버가 좋아요 누른 게시글 조회 /posts/me/likes

기능 수정사항

  • profile 뷰 삭제 -> me/list 뷰로 바꿈 (비공개 프로필)
