在新版本的 ClickHouse 中，多了一个名为 Replicated 的 Database Engine 类型。注意，是数据库的引擎，不是表引擎哦。...例如: CREATE DATABASE test_r ENGINE=Replicated('/clickhouse/dbs/test_r','01','ch9.nauu.com') 在不同的 ClickHouse...服务器节点上，拥有相同 Zookeeper path 的 Replicated Database，会自动同步创建 ReplicatedMergeTree 接下来用一个示例来演示 Replicated...要使用这项功能，首先要在配置中将其开启，在 user.xml 中增加: 1 在第一个节点创建 Replicated Database: ch9.nauu.com :) CREATE DATABASE test_r ENGINE=Replicated('/clickhouse
这些文件存储在单独的 non-replicated KahaDB 中。...如果将“延迟”和“计划任务消息”与 replicated LevelDB 一起使用，则会发生意外结果，因为该消息将不会复制到 Slave Broker 上，当主服务器故障转移到从服务器时，该数据将不存在...这里使用一台虚拟机创建不同的目录演示 1.2.2 修改配置文件 修改 broker 标签中的 brokerName 属性，使得集群中的 ActiveMQ brokerName 保持一致，然后注掉默认的 KahaDB 改为 replicated
