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).
