["FlyingZC (via GitHub)" <gi...@apache.org>]

FlyingZC opened a new issue, #26600:
URL: https://github.com/apache/shardingsphere/issues/26600

   ## Bug Report
   Unmodified tables are refreshed when metadata is modified.
   
   ### Which version of ShardingSphere did you use?
   Master
   
   ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
   Proxy
   
   ### Expected behavior
   Do not refresh unmodified tables.
   
   ### Actual behavior
   Unmodified tables are refreshed when metadata is modified.
   
   ### Reason analyze (If you can)
   ShardingSphereTable#getColumns is overrided to return `map.values`, `map.values` is `LinkedValues` type, the `equals` method is not overrided, resulting in `equals` is always false.
   ```java
   private final Map<String, ShardingSphereColumn> columns;
   public Collection<ShardingSphereColumn> getColumns() {
         return columns.values();
    }
   ```

   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   
   ### Example codes for reproduce this issue (such as a github link).
