CRDT - 텍스트 문서 실시간 동시 편집의 기본원리
동시문서편집 기술이란 무엇인가? 다들 한번씩은 사용해본 적이 있는 Google Docs를 생각해보면 감이 잡힐 것이다. 짧게 설명하자면, 단어 그대로, 동시에 서로가 문서를 편집할 수 있는 기술이다. 즉, 상대방이 무언가를 입력하면, 다른 사용자들(peer)이 그 입력하는 과정을 실시간으로 확인할 수 있고, 상대방이 문서를 편집하는 동시에 본인 또한 무언가를 입력하거나 수정이 가능한 문서 편집 기술이다. 컴퓨터에 대해서 잘 모르더라도, 동시에 같은 것을 작업하는 기술이기 때문에 사용자와 다른 사용자 사이에 정보가 왔다갔다해야 한다는 것은 대충 알 수 있다. 여기에서 기술적 난제는 ‘동시성’에서 발원한다. 이 `동시성`에서 발원하는 문제를 CRDT라는 알고리즘을 활용해서 해결한다.
