309593586 opened a new issue, #33711:
URL: https://github.com/apache/shardingsphere/issues/33711
see zhe following code:
```
public static Map<String, ShardingSphereDatabase> create(final Map<String,
DatabaseConfiguration> databaseConfigMap,
final
ConfigurationProperties props, final ComputeNodeInstanceContext
computeNodeInstanceContext) throws SQLException {
DatabaseType protocolType =
DatabaseTypeEngine.getProtocolType(databaseConfigMap, props);
SystemDatabase systemDatabase = new SystemDatabase(protocolType);
Map<String, ShardingSphereDatabase> result = new
ConcurrentHashMap<>(databaseConfigMap.size() +
systemDatabase.getSystemDatabaseSchemaMap().size(), 1F);
result.putAll(createGenericDatabases(databaseConfigMap,
protocolType, systemDatabase, props, computeNodeInstanceContext));
result.putAll(createSystemDatabases(databaseConfigMap, protocolType,
systemDatabase, props));
return result;
}
```
The variable “databaseConfigMap” contains multiple logical databases of
different types (specifically, Kingbase and MySQL logical databases), but the
method "DatabaseTypeEngine.getProtocolType()" only accommodates one database
type (MySQL).
