avalon566 opened a new issue #3710: Support scaling for shardingsphere
URL: https://github.com/apache/incubator-shardingsphere/issues/3710
 
 
   I missing an important work for sharding scaling. In order to support scaling for shardingsphere, We need to understand the sharding rule, and mapping the sharding table name to the actual table name.
   
   For sharding rule:
   
   ```
   t_order:
         actualDataNodes: ds${0..1}.t_order${0..1}
   ```
   
   We need synchronize table t_order0 and t_order1 from ds0, table t_order0 and t_order1 from ds1, this four table all map to t_order.
