	NetworkType *string

	// A value that indicates that the DB instance should be associated with the
	// specified option group. Permanent options, such as the TDE option for Oracle
	// Advanced Security TDE, can't be removed from an option group. Also, that option

	// instance. This setting doesn't apply to RDS Custom. Amazon Aurora Not

	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 daily time range during which automated backups are created if automated

	// Default: 1 Valid Values: 0 - 15
	PromotionTier *int32

	// A value that indicates whether the DB instance is publicly accessible. When the
	// DB instance is publicly accessible, its Domain Name System (DNS) endpoint
	// resolves to the private IP address from within the DB instance's virtual private
	// cloud (VPC). It resolves to the public IP address from outside of the DB
	// instance's VPC. Access to the DB instance is ultimately controlled by the
	// security group it uses. That public access is not permitted if the security
	// group assigned to the DB instance 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. Default: The default behavior varies depending on
	// whether DBSubnetGroupName is specified. If DBSubnetGroupName isn't specified,
	// and PubliclyAccessible isn't specified, the following applies:
	//
	// * If the default
	// VPC in the target Region doesn’t have an internet gateway attached to it, the DB
	// instance is private.
	//
	// * If the default VPC in the target Region has an internet
	// gateway attached to it, the DB instance is public.
	//
	// If DBSubnetGroupName is
	// specified, and PubliclyAccessible isn't specified, the following applies:
	//
	// * If
	// the subnets are part of a VPC that doesn’t have an internet gateway attached to
	// it, the DB instance is private.
	//
	// * If the subnets are part of a VPC that has an
	// internet gateway attached to it, the DB instance is public.
	PubliclyAccessible *bool

	// A value that indicates whether the DB instance is encrypted. By default, it
	// isn't encrypted. For RDS Custom instances, either set this parameter to true or
	// leave it unset. If you set this parameter to false, RDS reports an error. Amazon
	// Aurora Not applicable. The encryption for DB instances is managed by the DB
	// cluster.
	StorageEncrypted *bool

	// Specifies the storage type to be associated with the DB instance. Valid values:
	// standard | gp2 | io1 If you specify io1, you must also include a value for the
	// Iops parameter. Default: io1 if the Iops parameter is specified, otherwise gp2
	// Amazon Aurora Not applicable. Storage is managed by the DB cluster.
	StorageType *string

	// Tags to assign to the DB instance.
	Tags []types.Tag

	// The ARN from the key store with which to associate the instance for TDE
	// encryption. This setting doesn't apply to RDS Custom. Amazon Aurora Not

	TdeCredentialArn *string

	// The password for the given ARN from the key store in order to access the device.
	// This setting doesn't apply to RDS Custom.
