Member와 Team을 예로 생각했을 때 즉시로딩 -> Member만 필요해도 Team과 쿼리문이 같이 나감 지연로딩 -> Member만 불러오고, Team은 프록시 객체로 불러와서, Team이 필요할 때 영속성 컨텍스트에 연결을 요청하고 요청 쿼리문이 나가는 것이 맞나요 ? Member.getTeam().getName()을 1번 수행한다고 했을 때 즉시로딩 (Member + Team 쿼리문 같이)의 성능이 지연로딩 ( Member 쿼리문 따로, Team 쿼리문 따로)보다는 좋지만 강의에서 나온 여러가지 문제로 웬만해서는 지연로딩을 사용하는 것이 더 좋다. 이것이 맞나요?

ORDERS와 ORDER_ITEM의 관계는 하나의 주문 안에, 주문된 여러가지 아이템(book,album,movie등)이 있을 수 있기 때문에 1:N인 것 이 맞나요 ? OrderItem과 Item의 관계가 잘 이해 가지 않아서 찾아보다가 https://www.inflearn.com/course/lecture?courseSlug=ORM-JPA-Basic&unitId=21699&category=questionDetail&tab=community&q=805804 이 답변을 보고 헷갈리는 부분이 있는데요. Book을 n번 주문할 수 있기 때문에 1:N이라고 하셨는데 이 말은 즉, Book이라는 아이템 안에서도 주문된 여러가지 책(일본 책, 독일 책, 한국책) 이 있을 수 있기 때문에 1:N이라는 말일까요? 어떤 Member가 어떤 주문을 했는지 Order를 참고하는 것과 어떤 Order가 무엇을 구매했는지 Order_Item을 참고하는 것이 같은 맥락이라고 생각하는데 전자는 잘못된 설계고 후자는 괜찮은 설계인 이유는 무엇일까요?

안녕하세요! 제가 강의를 다 듣고 난 뒤 추가로 공부를 해볼 생각으로 catalog-service 에서 example-catalog-topic 를 받은 뒤 상품의 개수를 파악 후 재고 유무의 따라 order-service 에 주문 상태를 전달 해주는 example-order-topic 를 만들어 구독 중인 order-service 에서 example-order-topic 에서 전달 받은 주문 상태를 업데이트 하는 로직을 구현하려고 했습니다. 로컬에서 order-service 와 catalog-service 의 consumer groupId 를 consumerGroupId 로 통일해서 사용 했을 때는 괜찮았으나, docker 에 올리니 example-order-topic 이 생성은 됐으나 구독 및 전달이 되지 않더라구요.... 혹시나 해서 order-service 의 consumer groupId 를 consumerGroupId2 로 변경하여 docker 에 올리니 정상 작동이 됩니다. 혹시 각각의 service 는 groupId 를 다르게 해주어야 할까요??
