问题描述
我无法找到有关Zookeeper中持久性节点自动过期的信息.持久节点是仅在Zookeeper服务器关闭时才到期还是可以在此之前到期?如果是，可能的原因是什么?在这里，我要问的是自动到期而不是手动删除节点.

Is persistent node only expire when zookeeper server is shut down or it can expired before before that ?. if yes, what are the possible reason. Here I am asking about automatic expiration not manually deleting the node.
推荐答案
持久性ZK节点保存在磁盘上，并在服务重新启动时保留，并且仅在请求时删除.客户端断开连接后，临时节点会自动删除.
Persistent ZK nodes are saved on disk and preserved on service restarts and only deleted by request. Ephemeral nodes are deleted automatically on client disconnection.
