[GitHub] [shardingsphere] strongyc opened a new issue, #20845: Master-slave problem

strongyc opened a new issue, #20845:
URL: https://github.com/apache/shardingsphere/issues/20845

   ## Bug Report
   Using version 5.1.2, after configuring read-write separation and data fragmentation, the fragmented table cannot be read from the slave library, and other tables can read from the slave library normally. Why
   **For English only**, other languages will not accept.
   
   
   Before report a bug, make sure you have:
   
   - Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues).
   - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview).
   
   Please pay attention on issues you submitted, because we maybe need more details. 
   If no response anymore and we cannot reproduce it on current information, we will **close it**.
   
   Please answer these questions before submitting your issue. Thanks!
   
   ### Which version of ShardingSphere did you use?
   5.1.2
   
   ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
