## Question
```
@Subscribe
public synchronized void renew(final SchemaChangedEvent event) {
try {
Map<String, ShardingSphereMetaData> schemaMetaData = new
HashMap<>(metaDataContexts.getMetaDataMap().size(), 1);
for (Entry<String, ShardingSphereMetaData> entry :
metaDataContexts.getMetaDataMap().entrySet()) {
String schemaName = entry.getKey();
ShardingSphereMetaData originalMetaData = entry.getValue();
ShardingSphereMetaData metaData =
event.getSchemaName().equals(schemaName) ? getChangedMetaData(originalMetaData,
event.getSchema(), schemaName) : originalMetaData;
schemaMetaData.put(schemaName, metaData);
metaDataContexts.getOptimizeContextFactory().getSchemaMetadatas().getSchemas().put(event.getSchemaName(),
new FederateSchemaMetadata(event.getSchemaName(),
metaData.getSchema().getTables()));
}
metaDataContexts = new MetaDataContexts(persistService,
schemaMetaData,
metaDataContexts.getGlobalRuleMetaData(), metaDataContexts.getExecutorEngine(),
metaDataContexts.getProps(), metaDataContexts.getOptimizeContextFactory());
} finally {
ShardingSphereEventBus.getInstance().post(new
InnerLockReleasedEvent(LockNameUtil.getMetadataRefreshLockName()));
}
}
```
`FederateSchemaMetadata` should be rebuilt with **Actual MetaData** after
metadata changed, but the following code use Logic MetaData to create
`FederateSchemaMetadata`.
```
new FederateSchemaMetadata(event.getSchemaName(),
metaData.getSchema().getTables())
```
