CreateDBInstanceReadReplicaRequest

Indicates that minor engine upgrades will be applied automatically to the Read Replica during the maintenance window.

Default: Inherits from the source DB instance

The Amazon EC2 Availability Zone that the Read Replica will be created in.

Default: A random, system-chosen Availability Zone in the endpoint's region.

Example: us-east-1d

True to copy all tags from the Read Replica to snapshots of the Read Replica; otherwise false. The default is false.

The compute and memory capacity of the Read Replica.

Valid Values:

db.m1.small | db.m1.medium | db.m1.large | db.m1.xlarge | db.m2.xlarge
            |db.m2.2xlarge | db.m2.4xlarge | db.m3.medium | db.m3.large | db.m3.xlarge | db.m3.2xlarge
            | db.m4.large | db.m4.xlarge | db.m4.2xlarge | db.m4.4xlarge | db.m4.10xlarge | db.r3.large
            | db.r3.xlarge | db.r3.2xlarge | db.r3.4xlarge | db.r3.8xlarge | db.t2.micro | db.t2.small
            | db.t2.medium | db.t2.large

Default: Inherits from the source DB instance.

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.

Specifies a DB subnet group for the DB instance. The new DB instance will be created in the VPC associated with the DB subnet group. If no DB subnet group is specified, then the new DB instance is not created in a VPC.

Constraints:

• Can only be specified if the source DB instance identifier specifies a DB instance in another region.
• The specified DB subnet group must be in the same region in which the operation is running.
• All Read Replicas in one region that are created from the same source DB instance must either:
  • Specify DB subnet groups from the same VPC. All these Read Replicas will be created in the same VPC.
  • Not specify a DB subnet group. All these Read Replicas will be created outside of any VPC.

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

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 60.

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

The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to 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.

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

The option group the DB instance will be associated with. If omitted, the default option group for the engine specified will be used.

The port number that the DB instance uses for connections.

Default: Inherits from the source DB instance

Valid Values: 1150-65535

Specifies the accessibility options for the DB instance. A value of true specifies an Internet-facing instance with a publicly resolvable DNS name, which resolves to a public IP address. A value of false specifies an internal instance with a DNS name that resolves to a private IP address.

Default: The default behavior varies depending on whether a VPC has been requested or not. The following list shows the default behavior in each case.

• Default VPC:true
• VPC:false

If no DB subnet group has been specified as part of the request and the PubliclyAccessible value has not been set, the DB instance will be publicly accessible. If a specific DB subnet group has been specified as part of the request and the PubliclyAccessible value has not been set, the DB instance will be private.

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, or PostgreSQL DB instance.
• Can specify a DB instance that is a MySQL Read Replica only if the source is running MySQL 5.6.
• Can specify a DB instance that is a PostgreSQL Read Replica only if the source is running PostgreSQL 9.3.5.
• The specified DB instance must have automatic backups enabled, its backup retention period must be greater than 0.
• If the source DB instance is in the same region as the Read Replica, specify a valid DB instance identifier.
• If the source DB instance is in a different region than the Read Replica, specify a valid DB instance ARN. For more information, go to Constructing a Amazon RDS Amazon Resource Name (ARN).

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 standard
