Hash join in MySQL 8 For a long time, the only algorithm for executing a join in MySQL has been variations of the nested loop algorithm. With the release of MySQL 8.0.18, the server can now execute joins using hash join. This blog post will have a look at how it works, when it is used, and how it compares to the old join algorithms in MySQL in terms of performance.… Facebook Twitter LinkedIn Source: Hash join in MySQL 8

Amazon CloudWatch를 사용한 멀티 계정 및 리전간 교차 대시보드 기능 출시

Amazon CloudWatch를 사용한 멀티 계정 및 리전간 교차 대시보드 기능 출시 멀티 계정 또는 멀티 리전을 활용하여 개발 생산성 및 가용성을 높히는 것은 중요한 AWS 클라우드 배포에 대한 모범 사례 중 하나입니다. 멀티 계정을 사용하면 리소스를 서로 격리하고 문제가 발생했을 때 피해를 최소화하는 보안 및 결제 과정의 경계가 만들어집니다. 멀티 리전을 사용하면 격리 수준이 높아지고 최종 사용자의 지연 시간이 짧아지며 애플리케이션의 데이터 복구 능력이 향상됩니다. 하지만, 모니터링 및 문제 해결과 관련한 단점이 있습니다. 중앙 집중식 운영 팀, DevOps 엔지니어 및 서비스 소유자가 여러 리전과 수많은 계정에서 실행 중인 애플리케이션을 모니터링 및 분석하고 관련 문제를 해결해야 합니다. 경보가 수신되면 대기 중인 엔지니어가 대시보드에 로그인하여 문제를 진단하고 다른 계정에도 로그인해 다양한 구성 요소 또는 종속성에 대한 추가 대시보드를 확인해야 할 가능성이 큽니다. 서비스 소유자는 서비스 가용성에 영향을 미칠 수 있는 애플리케이션 리소스, 공유 리소스 또는 애플리케이션 간 종속성에 대한 가시성을 필요로 합니다.
