menghaoranss opened a new issue #12647:
URL: https://github.com/apache/shardingsphere/issues/12647
In class `ClusterContextManagerCoordinator`, when meta data just like data
source, rules and schema changed, the `MetaDataContext` is rebuilt by `new
MetaDataContexts`, and `StateContext` in `MetaDataContexts` is reset.
```
private MetaDataContexts rebuildMetaDataContexts(final Map<String,
ShardingSphereMetaData> schemaMetaData) {
Preconditions.checkState(contextManager.getMetaDataContexts().getMetaDataPersistService().isPresent());
return new
MetaDataContexts(contextManager.getMetaDataContexts().getMetaDataPersistService().get(),
schemaMetaData,
contextManager.getMetaDataContexts().getGlobalRuleMetaData(),
contextManager.getMetaDataContexts().getExecutorEngine(),
contextManager.getMetaDataContexts().getProps(),
contextManager.getMetaDataContexts().getOptimizerContext());
}
```
