이 경우 `startup` 이벤트 핸들러 함수는 단순히 몇 가지 값으로 구성된 `dict` 형식의 "데이터베이스"를 초기화합니다.

하나 이상의 이벤트 핸들러 함수를 추가할 수도 있습니다.

그리고 응용 프로그램은 모든 `startup` 이벤트 핸들러가 완료될 때까지 요청을 받지 않습니다.

## `shutdown` 이벤트

응용 프로그램이 종료될 때 실행하려는 함수를 추가하려면 `"shutdown"` 이벤트로 선언합니다:

MinIO supports persistent event store. The persistent store will backup events if MySQL connection goes offline and then replays the stored events when the broken connection comes back up. The event store can be configured by setting a directory path in `queue_dir` field, and the maximum number of events, which can be stored in a `queue_dir`, in `queue_limit` field. For example, `queue_dir` can be set to `/home/events` and `queue_limit` can be set to `1000`. By default,...
