// Reject new lock requests immediately when this many are queued
// for the local lock mutex.
// We do not block unlocking or maintenance, but they add to the count.
// The limit is set to allow for bursty behavior,

// Rejected clients are expected to retry.

// lockRequesterInfo stores various info from the client for each lock that is requested.

We will create the database tables when the application starts.

Here we create the tables on an application startup event.

For production you would probably use a migration script that runs before you start your app. 🤓

하지만 이로 인해 비동기 코드 작업이 훨씬 간단해졌습니다.

같은 (또는 거의 유사한) 문법은 최신 버전의 자바스크립트(브라우저와 NodeJS)에도 추가되었습니다.

하지만 그 이전에, 비동기 코드를 처리하는 것은 꽤 복잡하고 어려운 일이었습니다.

파이썬의 예전 버전이라면, 스레드 또는 <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>를 사용할 수 있을 것입니다. 하지만 코드를 이해하고, 디버깅하고, 이에 대해 생각하는게 훨씬 복잡합니다.

예전 버전의 NodeJS / 브라우저 자바스크립트라면, "콜백 함수"를 사용했을 것입니다. 그리고 이로 인해 "콜백 지옥"에 빠지게 될 수 있습니다.
