ADCC for zk可复制。与它协调的分布式进程一样 ,ADCC for zk本身旨在通过一组称为集成的主机进行复 制。组成ADCC for zk服务的服务器必须相互了解。 它们在持久存储中维护状态的内存映像以及事务日志和快 照。只要大多数服务器可用 ,ADCC for zk服务将可用。客户端连接到单个ADCC for zk服务器。客户端维护TCP连...
ZooKeeper 类有两个构造函数,我们这里使用“ ZooKeeper (String connectString, int sessionTimeout ,Watcher watcher )”对其进行初始化。因此,我们需要提供初始化所需的,连接字符串信息,会话超时时间,以及一个 watcher 实例。 19行到 25行代码,是程序所构造的一个watcher 实例,它能够输出所发生的事件。
