+ 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.

Required: No

 ** DBShardGroupArn **   
The Amazon Resource Name (ARN) for the DB shard group.  
Type: String  
Required: No

 ** DBShardGroupIdentifier **   
The name of the DB shard group.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 63.  
Pattern: `[a-zA-Z](?:-?[a-zA-Z0-9]+)*`   
Required: No

 ** DBShardGroupResourceId **   
The AWS Region-unique, immutable identifier for the DB shard group.  
Type: String  
Required: No

 ** Endpoint **   
The connection endpoint for the DB shard group.  
Type: String

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

Required: No

 ** MinACU **   
The minimum capacity of the DB shard group in Aurora capacity units (ACUs).  
Type: Double  
Required: No

 ** 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.

This setting is only for Aurora Limitless Database.
