总体介绍
- Oinone的读写分离方案是基于Sharding-JDBC的整合方案，要先具备一些Sharding-JDBC的知识。
[Sharding-JDBC] - 读写分离依赖于主从复制来同步数据，从库复制数据后，才能通过读写分离策略将读请求分发到从库，实现读写操作的分流，请根据业务需求自行实现主从配置。
配置读写策略
- 配置 top_demo 模块走读写分离的逻辑数据源 pamirsSharding。
- 配置数据源。
- 为 pamirsSharding 配置数据源以及 sharding 规则。
指定需要被sharding-jdbc接管的模块
指定top_demo模块给 Sharding-JDBC 接管，接管逻辑数据源名为 pamirsSharding
