+    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`_.

+            except in the following situation, and the change is asynchronously

+            cause a reboot, and the maintenance window is changed to include
+            the current time, then changing this parameter will cause a reboot
+            of the DB instance. If moving this window to the current time,
+            there must be at least 30 minutes between the current time and end
+            of the window to ensure pending changes are applied.

+
+        :type multi_az: boolean

+            Changing this parameter does not result in an outage and the change

+            `ApplyImmediately` parameter is set to `True` for this request.
+        Constraints: Cannot be specified if the DB instance is a read replica.
+
+        :type engine_version: string

+            DB parameter group can be the default for that DB parameter group
+            family.
+
+        Example: `5.1.42`
+
+        :type allow_major_version_upgrade: boolean

+            possible.
+        Constraints: This parameter must be set to true when specifying a value

+            than the DB instance's current version.
+
+        :type auto_minor_version_upgrade: boolean
+        :param auto_minor_version_upgrade: Indicates that minor version
+            upgrades will be applied automatically to the DB instance during

+            an outage except in the following case and the change is
+            asynchronously applied as soon as possible. An outage will result
+            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
+            for the RDS instance. Changing this parameter does not result in an
+            outage and the change is applied during the next maintenance window
+            unless the `ApplyImmediately` parameter is set to `True` for this
+            request.
+        Default: Uses existing setting
+
+        Constraints: Value supplied must be at least 10% greater than the
+            current value. Values that are not at least 10% greater than the
+            existing value are rounded up so that they are 10% greater than the
+            current value.
+
+        Type: Integer
+
+        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
