====== Redis Distributed Lock ======

===== Lettuce 기반 =====

  * [[nosql:redis:lettuce|Lettuce - Redis Java Client]] 는 공식적으로 분산 Lock 기능을 제공하지 않음.직접 구현 필요.
  * [[https://docs.spring.io/spring-integration/reference/html/redis.html|Spring Integration Redis Support]] 에서 lettuce 기반 분산 락 구현을 볼 수 있음.

  * Spin lock 과 pub/sub 기반이 있는데 spin lock 은 락을 획득할 때까지 계속해서 락을 획들할 수 있냐고 물어보는 방식이고, pub/sub 은 락 획득 실패시 메시징 기반으로 기다렸다가 획득가능해졌다는 메시지를 받으면 획득하는 방식.
  * pub/sub 방식이 더 좋다.

===== Redisson =====
  * [[nosql:redis:redisson|Redisson]]은 기본적으로 pub/sub 기반 분산 Lock을 제공해준다.
