-    Amazon Relational Database Service
-    Amazon Relational Database Service (Amazon RDS) is a web service
-    that makes it easier to set up, operate, and scale a relational
-    database in the cloud. It provides cost-efficient, resizable
-    capacity for an industry-standard relational database and manages
-    common database administration tasks, freeing up developers to
-    focus on what makes their applications and businesses unique.
-
-    Amazon RDS gives you access to the capabilities of a familiar
-    MySQL or Oracle database server. This means the code,
-    applications, and tools you already use today with your existing
-    MySQL or Oracle databases work with Amazon RDS without
-    modification. Amazon RDS automatically backs up your database and
-    maintains the database software that powers your DB instance.
-    Amazon RDS is flexible: you can scale your database instance's
-    compute resources and storage capacity to meet your application's
-    demand. As with all Amazon Web Services, there are no up-front
-    investments, and you pay only for the resources you use.
-
-    This is the Amazon RDS API Reference . It contains a comprehensive
-    description of all Amazon RDS Query APIs and data types. Note that
-    this API is asynchronous and some actions may require polling to
-    determine when an action has been applied. See the parameter
-    description to determine if a change is applied immediately or on
-    the next instance reboot or during the maintenance window. For
-    more information on Amazon RDS concepts and usage scenarios, go to
-    the `Amazon RDS User Guide`_.

-        If you choose to migrate your DB instance from using standard storage
-            to using Provisioned IOPS, or from using Provisioned IOPS to using
-            standard storage, the process can take time. The duration of the

-            size, storage type (standard or Provisioned IOPS), amount of IOPS
-            provisioned (if any), and the number of prior scale storage
-            operations. Typical migration times are under 24 hours, but the
-            process can take up to several days in some cases. During the
-            migration, the DB instance will be available for use, but may
-            experience performance degradation. While the migration takes
-            place, nightly backups for the instance will be suspended. No other

-            an outage except in the following case and the change is

-            if this parameter is set to `True` during the maintenance window,
-            and a newer minor version is available, and RDS has enabled auto
-            patching for that engine version.
-
-        :type iops: integer
-        :param iops: The new Provisioned IOPS (I/O operations per second) value

-        If you choose to migrate your DB instance from using standard storage
-            to using Provisioned IOPS, or from using Provisioned IOPS to using
-            standard storage, the process can take time. The duration of the
-            migration depends on several factors such as database load, storage
-            size, storage type (standard or Provisioned IOPS), amount of IOPS
-            provisioned (if any), and the number of prior scale storage
-            operations. Typical migration times are under 24 hours, but the
-            process can take up to several days in some cases. During the
-            migration, the DB instance will be available for use, but may
-            experience performance degradation. While the migration takes
-            place, nightly backups for the instance will be suspended. No other
-            Amazon RDS operations can take place for the instance, including
-            modifying the instance, rebooting the instance, deleting the
-            instance, creating a read replica for the instance, and creating a
-            DB snapshot of the instance.
-
-        :type option_group_name: string
-        :param option_group_name: Indicates that the DB instance should be
-            associated with the specified option group. Changing this parameter
-            does not result in an outage except in the following case and the
-            change is applied during the next maintenance window unless the
-            `ApplyImmediately` parameter is set to `True` for this request. If
-            the parameter change results in an option group that enables OEM,
-            this change can cause a brief (sub-second) period during which new
-            connections are rejected but existing connections are not
-            interrupted.
-        Permanent options, such as the TDE option for Oracle Advanced Security
-            TDE, cannot be removed from an option group, and that option group
