dbinstance_storage_type: Storage type. (e.g. local_ssd,general_essd,cloud_essd,cloud_essd2,cloud_essd3)
vpc_id: VPC ID.
vswitch_id: VSwitch ID.
private_ip_address: Private IP address.
client_token: Idempotence token.
resource_group_id: Resource group ID.
tde_status: TDE status (Enable, Disable).
encryption_key: Custom encryption key.
serverless_config: Serverless instance configuration.
table_names_case_sensitive: Are table names case-sensitive.
db_time_zone: the db instance time zone.
connection_string: the connection string for db instance.
db_param_group_id: the db param group id for db instance.
Returns:
Dict[str, Any]: Response containing the created instance details.Input Schema

Implementation Reference
- The handler function implementing the 'create_db_instance' MCP tool. It constructs a CreateDBInstanceRequest using Alibaba Cloud RDS SDK models and calls the API via get_rds_client to create a new RDS database instance.
