	// The Amazon Web Services KMS key identifier for an encrypted read replica. The

	// The interval, in seconds, between points when Enhanced Monitoring metrics are

	// RDS Custom.
	MonitoringRoleArn *string

	// A value that indicates whether the read replica is in a Multi-AZ deployment. You
	// can create a read replica as a Multi-AZ DB instance. RDS creates a standby of
	// your replica in another Availability Zone for failover support for the replica.
	// Creating your read replica as a Multi-AZ DB instance is independent of whether

	MultiAZ *bool

	// The network type of the DB instance. Valid values:
	//
	// * IPV4
	//
	// * DUAL
	//
	// The network
	// type is determined by the DBSubnetGroup specified for read replica. A
	// DBSubnetGroup can support only the IPv4 protocol or the IPv4 and the IPv6

	// (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_VPC.WorkingWithRDSInstanceinaVPC.html)
	// in the Amazon RDS User Guide.
	NetworkType *string

	// The option group the DB instance is associated with. If omitted, the option
	// group associated with the source instance is used. For SQL Server, you must use
	// the option group associated with the source instance. This setting doesn't apply
	// to RDS Custom.
	OptionGroupName *string

	// The Amazon Web Services KMS key identifier for encryption of Performance
	// Insights data. The Amazon Web Services KMS key identifier is the key ARN, key
	// ID, alias ARN, or alias name for the KMS key. If you do not specify a value for
	// PerformanceInsightsKMSKeyId, then Amazon RDS uses your default KMS key. There is
	// a default KMS key for your Amazon Web Services account. Your Amazon Web Services
	// account has a different default KMS key for each Amazon Web Services Region.
	// This setting doesn't apply to RDS Custom.
	PerformanceInsightsKMSKeyId *string

	// The number of days to retain Performance Insights data. The default is 7 days.
	// The following values are valid:
	//
	// * 7
	//
	// * month * 31, where month is a number of
	// months from 1-23
	//

	// months * 31)
	//
	// * 341 (11 months * 31)
	//
	// * 589 (19 months * 31)
	//
	// * 731
	//
	// If you
	// specify a retention period such as 94, which isn't a valid value, RDS issues an
	// error. This setting doesn't apply to RDS Custom.
	PerformanceInsightsRetentionPeriod *int32

	// The port number that the DB instance uses for connections. Default: Inherits
	// from the source DB instance Valid Values: 1150-65535
	Port *int32

	// When you are creating a read replica from one Amazon Web Services GovCloud (US)
	// Region to another or from one China Amazon Web Services Region to another, the
	// URL that contains a Signature Version 4 signed request for the
	// CreateDBInstanceReadReplica API operation in the source Amazon Web Services
	// Region that contains the source DB instance. This setting applies only to Amazon
	// Web Services GovCloud (US) Regions and China Amazon Web Services Regions. It's
	// ignored in other Amazon Web Services Regions. You must specify this parameter
	// when you create an encrypted read replica from another Amazon Web Services
	// Region by using the Amazon RDS API. Don't specify PreSignedUrl when you are
	// creating an encrypted read replica in the same Amazon Web Services Region. The
	// presigned URL must be a valid request for the CreateDBInstanceReadReplica API
	// operation that can run in the source Amazon Web Services Region that contains
	// the encrypted source DB instance. The presigned URL request must contain the
	// following parameter values:
	//
	// * DestinationRegion - The Amazon Web Services
	// Region that the encrypted read replica is created in. This Amazon Web Services
	// Region is the same one where the CreateDBInstanceReadReplica operation is called
	// that contains this presigned URL. For example, if you create an encrypted DB
	// instance in the us-west-1 Amazon Web Services Region, from a source DB instance
	// in the us-east-2 Amazon Web Services Region, then you call the
	// CreateDBInstanceReadReplica operation in the us-east-1 Amazon Web Services
	// Region and provide a presigned URL that contains a call to the
	// CreateDBInstanceReadReplica operation in the us-west-2 Amazon Web Services
	// Region. For this example, the DestinationRegion in the presigned URL must be set
	// to the us-east-1 Amazon Web Services Region.
	//
	// * KmsKeyId - The KMS key
	// identifier for the key to use to encrypt the read replica in the destination
	// Amazon Web Services Region. This is the same identifier for both the
	// CreateDBInstanceReadReplica operation that is called in the destination Amazon
	// Web Services Region, and the operation contained in the presigned URL.
	//
	// *
	// SourceDBInstanceIdentifier - The DB instance identifier for the encrypted DB
	// instance to be replicated. This identifier must be in the Amazon Resource Name
	// (ARN) format for the source Amazon Web Services Region. For example, if you are
	// creating an encrypted read replica from a DB instance in the us-west-2 Amazon
	// Web Services Region, then your SourceDBInstanceIdentifier looks like the
	// following example:
	// arn:aws:rds:us-west-2:123456789012:instance:mysql-instance1-20161115.
	//
	// To learn
	// how to generate a Signature Version 4 signed request, see Authenticating
	// Requests: Using Query Parameters (Amazon Web Services Signature Version 4)
	// (https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-query-string-auth.html)
	// and Signature Version 4 Signing Process
	// (https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html). If you
	// are using an Amazon Web Services SDK tool or the CLI, you can specify
	// SourceRegion (or --source-region for the CLI) instead of specifying PreSignedUrl
	// manually. Specifying SourceRegion autogenerates a presigned URL that is a valid
	// request for the operation that can run in the source Amazon Web Services Region.
	// SourceRegion isn't supported for SQL Server, because Amazon RDS for SQL Server
	// doesn't support cross-Region read replicas. This setting doesn't apply to RDS
	// Custom.
	PreSignedUrl *string

	// The number of CPU cores and the number of threads per core for the DB instance
	// class of the DB instance. This setting doesn't apply to RDS Custom.
	ProcessorFeatures []types.ProcessorFeature

	// A value that indicates whether the DB instance is publicly accessible. When the
	// DB cluster is publicly accessible, its Domain Name System (DNS) endpoint
	// resolves to the private IP address from within the DB cluster's virtual private
	// cloud (VPC). It resolves to the public IP address from outside of the DB
	// cluster's VPC. Access to the DB cluster is ultimately controlled by the security
	// group it uses. That public access isn't permitted if the security group assigned
	// to the DB cluster doesn't permit it. When the DB instance isn't publicly
	// accessible, it is an internal DB instance with a DNS name that resolves to a
	// private IP address. For more information, see CreateDBInstance.
	PubliclyAccessible *bool

	// The open mode of the replica database: mounted or read-only. This parameter is
	// only supported for Oracle DB instances. Mounted DB replicas are included in
	// Oracle Database Enterprise Edition. The main use case for mounted replicas is
	// cross-Region disaster recovery. The primary database doesn't use Active Data
	// Guard to transmit information to the mounted replica. Because it doesn't accept
	// user connections, a mounted replica can't serve a read-only workload. You can
	// create a combination of mounted and read-only DB replicas for the same primary
	// DB instance. For more information, see Working with Oracle Read Replicas for
	// Amazon RDS
	// (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/oracle-read-replicas.html)

	// creation, you can manage the open mode manually.
	ReplicaMode types.ReplicaMode

	// The AWS region the resource is in. The presigned URL will be created with this
	// region, if the PresignURL member is empty set.
	SourceRegion *string

	// Specifies the storage type to be associated with the read replica. Valid values:
	// standard | gp2 | io1 If you specify io1, you must also include a value for the
