동일한 기반 하드웨어에서 실행됩니다.
각 마이크로서비스 인스턴스는 자신에게 할당된 파티션의 이벤트를 구체화하고 상태 저장소
내부에서 각 파티션별 데이터를 논리적으로 분리합니다. 이렇게 파티션을 논리적으로 나누어
구체화하기 때문에 마이크로서비스 인스턴스는 컨슈머 그룹 리밸런스 이후 회수된 파티션의
상태를 그냥 삭제할 수 있습니다. 구체화 상태는 파티션을 소유한 인스턴스에만 존재하므로 리
소스 누수가 생기고 진실 공급원이 쪼개지는 불상사도 막을 수 있죠. 파티션이 새로 할당되면
이벤트 스트림이나 체인지로그의 입력 이벤트를 소비해서 재구성할 수도 있습니다.
