/**

 *
 * 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 database server. This means the code, applications, and tools you
 * already use today with your existing MySQL 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 API is used to change RDS Instance settings. Users call the ModifyDBInstance API to change one or more database configuration
	 * parameters by specifying these parameters and the new values in the request.
	 *
	 * @param string $db_instance_identifier (Required) The DB Instance identifier. This value is stored as a lowercase string. Constraints: <ul> <li>Must contain from 1 to 63 alphanumeric characters or hyphens</li><li>First character must be a letter</li><li>Cannot end with a hyphen or contain two consecutive hyphens</li> </ul> Example: <copy>mydbinstance</copy>
	 * @param array $opt (Optional) An associative array of parameters that can have the following keys: <ul>
	 * 	<li><code>AllocatedStorage</code> - <code>integer</code> - Optional - The new storage capacity of the RDS instance. This change does not result in an outage and is applied during the next maintenance window unless the <code>ApplyImmediately</code> parameter is specified as <code>true</code> for this request. Default: Uses existing setting Valid Values: 5-1024 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. </li>
	 * 	<li><code>DBInstanceClass</code> - <code>string</code> - Optional - The new compute and memory capacity of the DB Instance. Passing a value for this parameter causes an outage during the change and is applied during the next maintenance window, unless the <code>ApplyImmediately</code> parameter is specified as <code>true</code> for this request. Default: Uses existing setting Valid Values: <code>db.m1.small | db.m1.large | db.m1.xlarge | db.m2.xlarge | db.m2.2xlarge | db.m2.4xlarge</code> </li>
	 * 	<li><code>DBSecurityGroups</code> - <code>string|array</code> - Optional - A list of DB Security Groups to authorize on this DB Instance. This change is asynchronously applied as soon as possible. Constraints: <ul> <li>Must be 1 to 255 alphanumeric characters</li><li>First character must be a letter</li><li>Cannot end with a hyphen or contain two consecutive hyphens</li> </ul>  Pass a string for a single value, or an indexed array for multiple values. </li>
	 * 	<li><code>ApplyImmediately</code> - <code>boolean</code> - Optional - Specifies whether or not the modifications in this request and any pending modifications are asynchronously applied as soon as possible, regardless of the <code>PreferredMaintenanceWindow</code> setting for the DB Instance. If this parameter is passed as <code>false</code>, changes to the DB Instance are applied on the next call to RebootDBInstance, the next maintenance reboot, or the next failure reboot, whichever occurs first. Default: <code>false</code> </li>
	 * 	<li><code>MasterUserPassword</code> - <code>string</code> - Optional - The new password for the DB Instance master user. This change is asynchronously applied as soon as possible. Between the time of the request and the completion of the request, the <code>MasterUserPassword</code> element exists in the <code>PendingModifiedValues</code> element of the operation response. Default: Uses existing setting Constraints: Must be 4 to 41 alphanumeric characters (engine specific) Amazon RDS APIs never return the password, so this API provides a way to regain access to a master instance user if the password is lost. </li>
	 * 	<li><code>DBParameterGroupName</code> - <code>string</code> - Optional - The name of the DB Parameter Group to apply to this DB Instance. This change is asynchronously applied as soon as possible for parameters when the <i>ApplyImmediately</i> parameter is specified as <code>true</code> for this request. Default: Uses existing setting Constraints: The DB Parameter Group must be in the same DB Parameter Group family as this DB Instance. </li>
	 * 	<li><code>BackupRetentionPeriod</code> - <code>integer</code> - Optional - The number of days to retain automated backups. Setting this parameter to a positive number enables backups. Setting this parameter to 0 disables automated backups. Default: Uses existing setting Constraints: <ul> <li>Must be a value from 0 to 8</li><li>Cannot be set to 0 if the DB Instance is a master instance with read replicas or of the DB Instance is a read replica</li> </ul> </li>
	 * 	<li><code>PreferredBackupWindow</code> - <code>string</code> - Optional - The daily time range during which automated backups are created if automated backups are enabled, as determined by the <code>BackupRetentionPeriod</code>. Constraints: <ul> <li>Must be in the format hh24:mi-hh24:mi</li><li>Times should be Universal Time Coordinated (UTC)</li><li>Must not conflict with the preferred maintenance window</li><li>Must be at least 30 minutes</li> </ul> </li>
	 * 	<li><code>PreferredMaintenanceWindow</code> - <code>string</code> - Optional - The weekly time range (in UTC) during which system maintenance can occur, which may result in an outage. This change is made immediately. 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. Default: Uses existing setting Format: ddd:hh24:mi-ddd:hh24:mi Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun Constraints: Minimum 30 minute period </li>
	 * 	<li><code>MultiAZ</code> - <code>boolean</code> - Optional - Specifies if the DB Instance is a Multi-AZ deployment. Constraints: Cannot be specified if the DB Instance is a read replica. </li>
	 * 	<li><code>EngineVersion</code> - <code>string</code> - Optional - The version number of the database engine to upgrade to. For major version upgrades, if a nondefault DB Parameter Group is currently in use, a new DB Parameter Group in the DB Parameter Group Family for the new engine version must be specified.

	 * 	<li><code>AllowMajorVersionUpgrade</code> - <code>boolean</code> - Optional - Indicates that major version upgrades are allowed. Constraints: This parameter must be set to true when specifying a value for the EngineVersion parameter that is a different major version than the DB Instance's current version. </li>
	 * 	<li><code>AutoMinorVersionUpgrade</code> - <code>boolean</code> - Optional - Indicates that minor version upgrades will be applied automatically to the DB Instance during the maintenance window. </li>
	 * 	<li><code>curlopts</code> - <code>array</code> - Optional - A set of values to pass directly into <php:curl_setopt()>, where the key is a pre-defined <code>CURLOPT_*</code> constant.</li>
	 * 	<li><code>returnCurlHandle</code> - <code>boolean</code> - Optional - A private toggle specifying that the cURL handle be returned rather than actually completing the request. This toggle is useful for manually managed batch requests.</li></ul>
