尽可能的保证 7*24 小时不间断的数据库服务，是 Apache ShardingSphere 高可用模块的主要设计目标。
+## 应用场景
+
+在大多数情况下，高可用搭配读写分离功能一起使用。当用户写库或读库关系发生变化时，ShardingSphere
可动态的感知并纠正内部的主从关系，进而保证读流量和写流量的正确路由。同时当从库宕机时，ShardingSphere
也可动态纠正存储节点的状态，保证读流量分发正确。

The main goal of Apache ShardingSphere high availability module which is
ensuring 7 * 24-hour uninterrupted database service as much as possible.
+## Application Scenarios
+
+In most cases, high availability is used in conjunction with read/write
splitting. When the relationship between users' write database and read
database changes, ShardingSphere dynamically senses and corrects the internal
primary/secondary relationship, thus ensuring the correct routing of the read
and write traffic. At the same time, when the secondary database breaks down,
ShardingSphere can also dynamically correct the state of storage nodes to
ensure correct distribution of the read [...]
