CreateDBShardGroup

Creates a new DB shard group for Aurora Limitless Database. You must enable Aurora Limitless Database to create a DB shard group.

Valid for: Aurora DB clusters only

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

DBClusterIdentifier

The name of the primary DB cluster for the DB shard group.

Type: String

Required: Yes

DBShardGroupIdentifier

The name of the DB shard group.

Type: String

Required: Yes

MaxACU

The maximum capacity of the DB shard group in Aurora capacity units (ACUs).

Type: Double

Required: Yes

ComputeRedundancy

Specifies whether to create standby DB shard groups for the DB shard group. Valid values are the following:

0 - Creates a DB shard group without a standby DB shard group. This is the default value.
1 - Creates a DB shard group with a standby DB shard group in a different Availability Zone (AZ).
2 - Creates a DB shard group with two standby DB shard groups in two different AZs.

Type: Integer

Required: No

MinACU

The minimum capacity of the DB shard group in Aurora capacity units (ACUs).

Type: Double

Required: No

PubliclyAccessible

Specifies whether the DB shard group is publicly accessible.

When the DB shard group is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB shard group's virtual private cloud (VPC). It resolves to the public IP address from outside of the DB shard group's VPC. Access to the DB shard group is ultimately controlled by the security group it uses. That public access is not permitted if the security group assigned to the DB shard group doesn't permit it.

When the DB shard group isn't publicly accessible, it is an internal DB shard group 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 shard group is private.
If the default VPC in the target Region has an internet gateway attached to it, the DB shard group 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 shard group is private.
If the subnets are part of a VPC that has an internet gateway attached to it, the DB shard group is public.

Type: Boolean

Required: No

Tags.Tag.N

A list of tags.

For more information, see Tagging Amazon RDS resources in the Amazon RDS User Guide or Tagging Amazon Aurora and Amazon RDS resources in the Amazon Aurora User Guide.

Type: Array of Tag objects

Required: No

Type: String

DBShardGroupArn

The Amazon Resource Name (ARN) for the DB shard group.

Type: String

DBShardGroupResourceId

The AWS Region-unique, immutable identifier for the DB shard group.

Type: String

Endpoint

The connection endpoint for the DB shard group.

Type: String

Type: Double

MinACU

The minimum capacity of the DB shard group in Aurora capacity units (ACUs).

Type: Double

PubliclyAccessible

Indicates whether the DB shard group is publicly accessible.

When the DB shard group is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB shard group's virtual private cloud (VPC). It resolves to the public IP address from outside of the DB shard group's VPC. Access to the DB shard group is ultimately controlled by the security group it uses. That public access isn't permitted if the security group assigned to the DB shard group doesn't permit it.

When the DB shard group isn't publicly accessible, it is an internal DB shard group with a DNS name that resolves to a private IP address.

For more information, see CreateDBShardGroup.

This setting is only for Aurora Limitless Database.

Type: Boolean

Status

The status of the DB shard group.

Type: String

TagList.Tag.N

A list of tags.
