NAME

Paws::RDS::CreateDBInstanceReadReplica - Arguments for method CreateDBInstanceReadReplica on Paws::RDS

DESCRIPTION

This class represents the parameters used for calling the method CreateDBInstanceReadReplica on the Amazon Relational Database Service service. Use the attributes of this class as arguments to method CreateDBInstanceReadReplica.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to CreateDBInstanceReadReplica.

SYNOPSIS

my $rds = Paws->service('RDS');
# To create a DB instance read replica.
# This example creates a DB instance read replica.
my $CreateDBInstanceReadReplicaResult = $rds->CreateDBInstanceReadReplica(
  'AvailabilityZone'           => 'us-east-1a',
  'CopyTagsToSnapshot'         => 1,
  'DBInstanceClass'            => 'db.t2.micro',
  'DBInstanceIdentifier'       => 'mydbreadreplica',
  'PubliclyAccessible'         => 1,
  'SourceDBInstanceIdentifier' => 'mymysqlinstance',
  'StorageType'                => 'gp2',
  'Tags'                       => [

    {
      'Key'   => 'mydbreadreplicakey',
      'Value' => 'mydbreadreplicavalue'
    }
  ]
);

# Results:
my $DBInstance = $CreateDBInstanceReadReplicaResult->DBInstance;

# Returns a L<Paws::RDS::CreateDBInstanceReadReplicaResult> object.

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/rds/CreateDBInstanceReadReplica

ATTRIBUTES

AutoMinorVersionUpgrade => Bool

A value that indicates whether minor engine upgrades are applied automatically to the read replica during the maintenance window.

Default: Inherits from the source DB instance

AvailabilityZone => Str

The Availability Zone (AZ) where the read replica will be created.

Default: A random, system-chosen Availability Zone in the endpoint's Amazon Web Services Region.

Example: us-east-1d

CopyTagsToSnapshot => Bool

A value that indicates whether to copy all tags from the read replica to snapshots of the read replica. By default, tags are not copied.

DBInstanceClass => Str

The compute and memory capacity of the read replica, for example, db.m4.large. Not all DB instance classes are available in all Amazon Web Services Regions, or for all database engines. For the full list of DB instance classes, and availability for your engine, see DB Instance Class (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.DBInstanceClass.html) in the Amazon RDS User Guide.

Default: Inherits from the source DB instance.

REQUIRED DBInstanceIdentifier => Str

The DB instance identifier of the read replica. This identifier is the unique key that identifies a DB instance. This parameter is stored as a lowercase string.

DBParameterGroupName => Str

The name of the DB parameter group to associate with this DB instance.

If you do not specify a value for DBParameterGroupName, then Amazon RDS uses the DBParameterGroup of source DB instance for a same region read replica, or the default DBParameterGroup for the specified DB engine for a cross region read replica.

Currently, specifying a parameter group for this operation is only supported for Oracle DB instances.

Constraints:

  • Must be 1 to 255 letters, numbers, or hyphens.

  • First character must be a letter

  • Can't end with a hyphen or contain two consecutive hyphens

DBSubnetGroupName => Str

Specifies a DB subnet group for the DB instance. The new DB instance is created in the VPC associated with the DB subnet group. If no DB subnet group is specified, then the new DB instance isn't created in a VPC.

Constraints:

  • Can only be specified if the source DB instance identifier specifies a DB instance in another Amazon Web Services Region.

  • If supplied, must match the name of an existing DBSubnetGroup.

  • The specified DB subnet group must be in the same Amazon Web Services Region in which the operation is running.

  • All read replicas in one Amazon Web Services Region that are created from the same source DB instance must either:>

    • Specify DB subnet groups from the same VPC. All these read replicas are created in the same VPC.

    • Not specify a DB subnet group. All these read replicas are created outside of any VPC.

Example: mySubnetgroup

DeletionProtection => Bool

A value that indicates whether the DB instance has deletion protection enabled. The database can't be deleted when deletion protection is enabled. By default, deletion protection is disabled. For more information, see Deleting a DB Instance (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_DeleteInstance.html).

Domain => Str

The Active Directory directory ID to create the DB instance in. Currently, only MySQL, Microsoft SQL Server, Oracle, and PostgreSQL DB instances can be created in an Active Directory Domain.

For more information, see Kerberos Authentication (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/kerberos-authentication.html) in the Amazon RDS User Guide.

DomainIAMRoleName => Str

Specify the name of the IAM role to be used when making API calls to the Directory Service.

EnableCloudwatchLogsExports => ArrayRef[Str|Undef]

The list of logs that the new DB instance is to export to CloudWatch Logs. The values in the list depend on the DB engine being used. For more information, see Publishing Database Logs to Amazon CloudWatch Logs (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_LogAccess.html#USER_LogAccess.Procedural.UploadtoCloudWatch) in the Amazon RDS User Guide.

EnableIAMDatabaseAuthentication => Bool

A value that indicates whether to enable mapping of Amazon Web Services Identity and Access Management (IAM) accounts to database accounts. By default, mapping is disabled.

For more information about IAM database authentication, see IAM Database Authentication for MySQL and PostgreSQL (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.IAMDBAuth.html) in the Amazon RDS User Guide.

EnablePerformanceInsights => Bool

A value that indicates whether to enable Performance Insights for the read replica.

For more information, see Using Amazon Performance Insights (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_PerfInsights.html) in the Amazon RDS User Guide.

Iops => Int

The amount of Provisioned IOPS (input/output operations per second) to be initially allocated for the DB instance.

KmsKeyId => Str

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

The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the Amazon Web Services KMS CMK.

If you create an encrypted read replica in the same Amazon Web Services Region as the source DB instance, then do not specify a value for this parameter. A read replica in the same Region is always encrypted with the same Amazon Web Services KMS CMK as the source DB instance.

If you create an encrypted read replica in a different Amazon Web Services Region, then you must specify a Amazon Web Services KMS key identifier for the destination Amazon Web Services Region. Amazon Web Services KMS CMKs are specific to the Amazon Web Services Region that they are created in, and you can't use CMKs from one Amazon Web Services Region in another Amazon Web Services Region.

You can't create an encrypted read replica from an unencrypted DB instance.

MaxAllocatedStorage => Int

The upper limit to which Amazon RDS can automatically scale the storage of the DB instance.

For more information about this setting, including limitations that apply to it, see Managing capacity automatically with Amazon RDS storage autoscaling (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_PIOPS.StorageTypes.html#USER_PIOPS.Autoscaling) in the Amazon RDS User Guide.

MonitoringInterval => Int

The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the read replica. To disable collecting Enhanced Monitoring metrics, specify 0. The default is 0.

If MonitoringRoleArn is specified, then you must also set MonitoringInterval to a value other than 0.

Valid Values: 0, 1, 5, 10, 15, 30, 60

MonitoringRoleArn => Str

The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to Amazon CloudWatch Logs. For example, arn:aws:iam:123456789012:role/emaccess. For information on creating a monitoring role, go to To create an IAM role for Amazon RDS Enhanced Monitoring (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Monitoring.html#USER_Monitoring.OS.IAMRole) in the Amazon RDS User Guide.

If MonitoringInterval is set to a value other than 0, then you must supply a MonitoringRoleArn value.

MultiAZ => Bool

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 the source database is a Multi-AZ DB instance.

OptionGroupName => Str

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.

PerformanceInsightsKMSKeyId => Str

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 Amazon Web Services KMS customer master key (CMK).

If you do not specify a value for PerformanceInsightsKMSKeyId, then Amazon RDS uses your default CMK. There is a default CMK for your Amazon Web Services account. Your Amazon Web Services account has a different default CMK for each Amazon Web Services Region.

PerformanceInsightsRetentionPeriod => Int

The amount of time, in days, to retain Performance Insights data. Valid values are 7 or 731 (2 years).

Port => Int

The port number that the DB instance uses for connections.

Default: Inherits from the source DB instance

Valid Values: 1150-65535

PreSignedUrl => Str

The URL that contains a Signature Version 4 signed request for the CreateDBInstanceReadReplica API action in the source Amazon Web Services Region that contains the source DB instance.

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 action that can be executed 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 action 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 action in the us-east-1 Amazon Web Services Region and provide a presigned URL that contains a call to the CreateDBInstanceReadReplica action 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 Amazon Web Services 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 action that is called in the destination Amazon Web Services Region, and the action 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 be executed in the source Amazon Web Services Region.

SourceRegion isn't supported for SQL Server, because SQL Server on Amazon RDS doesn't support cross-region read replicas.

ProcessorFeatures => ArrayRef[Paws::RDS::ProcessorFeature]

The number of CPU cores and the number of threads per core for the DB instance class of the DB instance.

PubliclyAccessible => Bool

A value that indicates whether the DB instance is publicly accessible.

When the DB instance is publicly accessible, its DNS endpoint resolves to the private IP address from within the DB instance's VPC, and 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, and 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.

For more information, see CreateDBInstance.

ReplicaMode => Str

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 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) in the Amazon RDS User Guide.

Valid values are: "open-read-only", "mounted"

REQUIRED SourceDBInstanceIdentifier => Str

The identifier of the DB instance that will act as the source for the read replica. Each DB instance can have up to five read replicas.

Constraints:

  • Must be the identifier of an existing MySQL, MariaDB, Oracle, PostgreSQL, or SQL Server DB instance.

  • Can specify a DB instance that is a MySQL read replica only if the source is running MySQL 5.6 or later.

  • For the limitations of Oracle read replicas, see Read Replica Limitations with Oracle (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/oracle-read-replicas.html) in the Amazon RDS User Guide.

  • For the limitations of SQL Server read replicas, see Read Replica Limitations with Microsoft SQL Server (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/SQLServer.ReadReplicas.Limitations.html) in the Amazon RDS User Guide.

  • Can specify a PostgreSQL DB instance only if the source is running PostgreSQL 9.3.5 or later (9.4.7 and higher for cross-region replication).

  • The specified DB instance must have automatic backups enabled, that is, its backup retention period must be greater than 0.

  • If the source DB instance is in the same Amazon Web Services Region as the read replica, specify a valid DB instance identifier.

  • If the source DB instance is in a different Amazon Web Services Region from the read replica, specify a valid DB instance ARN. For more information, see Constructing an ARN for Amazon RDS (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Tagging.ARN.html#USER_Tagging.ARN.Constructing) in the Amazon RDS User Guide. This doesn't apply to SQL Server, which doesn't support cross-region replicas.

StorageType => Str

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 Iops parameter.

Default: io1 if the Iops parameter is specified, otherwise gp2

Tags => ArrayRef[Paws::RDS::Tag]

UseDefaultProcessorFeatures => Bool

A value that indicates whether the DB instance class of the DB instance uses its default processor features.

VpcSecurityGroupIds => ArrayRef[Str|Undef]

A list of EC2 VPC security groups to associate with the read replica.

Default: The default EC2 VPC security group for the DB subnet group's VPC.
