실습으로 배우는 선착순 이벤트 시스템
안녕하세요 강의를 듣다가 궁금증이 생겼는데요. kafka는 메시지를 하나씩 처리하기 때문에 동시성 제어도 가능할 것이라고 이해했는데 그렇다면 여기서 레디스를 사용하지 않더라도 카프카만 사용해도 동시성과 관련된 데이터 정합성을 보장할 수 있는건가요?

Collection.Map의 Good 케이스를 알 수 있을까요? 맵을 사용할 때 맵 안에 맵이 있고 이런 형태를 사용하지 않는게 좋은건지 아니면 따로 dto로 변환해서 사용해야하는건지 구분이 안 가서 질문 드립니다 ! 지정된 scope를 넘나들지 않는다는 것도 이해가 가지 않습니다 ㅠㅠ 조금만 더 쉽게 설명 붙여주시면 감사드리겠습니다!

이전 강의까진 npx cli가 작동이 잘 되었는데 이번 강의 코드에선 npx cli -v 하니깐 에러가 나는 것도 아니고 아무것도 안 뜨고 그냥 이렇게 끝나는데 이거 해결법이 있나요? 물론 node command -v는 잘 작동이 됩니다.

클래스의 상속과 관련된 다형성은 부모객체로 인스턴스를 생성하여 부모클래스의 메소드와 자식클래스 메소드 2가지를 업/다운캐스팅하여 자유롭게 호출할 수 있지만, 단일상속이라는 한계 때문에 다른 부모클래스의 메소드는 호출할 수가 없잖아요? 그래서 인터페이스가 존재하는 이유구요. 마찬가지로, 인스턴스를 생성할 때 다형성을 활용하여 인터페이스 객체(부모 객체)로 생성할 수는 있지만, 이것은 ISP(Interface Segregation Principle)원칙에 따라 detect(), report() 2개의 메소드를 호출하려면 Detectable, Reportable 객체 2개를 생성해야 하기 때문에 메모리가 효율적으로 관리되지 못하는거구요. 따라서 구상클래스인 FactoryCam에서 인터페이스 변수를 직접 생성하고 setter함수로 필요한 인터페이스 변수를 주입한 다음(Dependency Injection) , 주입당한 객체는 인터페이스에 의존하기 때문에(Reportable, Detectable) 동시에 기능이 다른 2가지 메소드를 호출할 수 있는거구요.(Dependency Inversion Principle) ... 과정을 이해하였지만 말로 풀어내니까 굉장히 장황하군요 사실 이 부분은 인터페이스 문법이라기보다는 디자인 패턴과 관련이 있지 않나싶습니다.

아직 노드버드 ch10 진행중입니다. 진행하면서 다른 글들도 참고하면서 진행중인데요 async await 사용 방식에 대해 문의드립니다.

강의 7:40부근 webpack.config.ts 파일 72번째 라인 devServer: { historyApiFallback: true, // react router port: 3090, devMiddleware: { publicPath: '/dist/' }, static: { directory: path.resolve(__dirname) }, }, 이부분 추가하시면 될것같습니다. static: { directory: path.resolve(__dirname) }

무료/프리미엄 고르고 도메인주소 입력하면 밑에 화면에 주소와 타입 비밀키가 표시되지 않습니다. 로그는 계속 이렇게만 뜨고, 워크벤치 들어가보면 키는 보입니다. 키가 발급은 되었는데, 브라우저로 못 띄우는 것 같다고 판단했습니다. 어떤 부분을 확인해봐야 될까요?

로그인 및 인증,인가(세션,jwt둘다 사용), 게시판(이미지포함), 댓글, 소켓채팅 정도의 기능을 구현하여 테스트 코드와 docker로 띄워서 CI/CD까지 구현하려고 합니다. 상태랑 로직 관리를 useReducer, React Context API, React Query, redux, graphql 정도로 생각하고 있는데 어떤걸로 하는게 좋을까요?!

[질문 내용] 여기에 질문 내용을 남겨주세요. 1. Tasks - other에 compileQuerydsl이 없어서 compileJava를 눌러서 했는데 괜찮은지 ?? 2.강사님과 다르게 build /generated 이렇게 생성되어도 문제가 없는지? 저런식으로 Q파일들이 생성되었는데 import가 안되고 사용이 안되는 이유 알려주시면 감사하겠습니다.
