	//
	// The presigned URL must be a valid request for the CreateDBInstanceReadReplica

	//
	// For example, if you create an encrypted DB instance in the us-west-1 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
