You can set this value only on Aurora DB clusters that are members of an Aurora global database. With this parameter enabled, a secondary cluster can forward writes to the current primary cluster, and the resulting changes are replicated back to this cluster. For the primary DB cluster of an Aurora global database, this value is used immediately if the primary is demoted by a global cluster API operation, but it does nothing until then.

Valid for Cluster Type: Aurora DB clusters only
DBClusterInstanceClass (string) –
The compute and memory capacity of each DB instance in the Multi-AZ DB cluster, for example db.m6gd.xlarge. Not all DB instance classes are available in all Amazon Web Services Regions, or for all database engines.

This setting is valid only if the master user password is managed by RDS in Amazon Web Services Secrets Manager for the DB cluster. The secret value contains the updated password.

For more information, see Password management with Amazon Web Services Secrets Manager in the Amazon RDS User Guide and Password management with Amazon Web Services Secrets Manager in the Amazon Aurora User Guide.

Valid for Cluster Type: Aurora DB clusters and Multi-AZ DB clusters

Constraints:
- You must apply the change immediately when rotating the master user password.
MasterUserSecretKmsKeyId (string) –
The Amazon Web Services KMS key identifier to encrypt a secret that is automatically generated and managed in Amazon Web Services Secrets Manager.

This setting is valid only if both of the following conditions are met:
- The DB cluster doesn’t manage the master user password in Amazon Web Services Secrets Manager. If the DB cluster already manages the master user password in Amazon Web Services Secrets Manager, you can’t change the KMS key that is used to encrypt the secret.
- You are turning on ManageMasterUserPassword to manage the master user password in Amazon Web Services Secrets Manager. If you are turning on ManageMasterUserPassword and don’t specify MasterUserSecretKmsKeyId, then the aws/secretsmanager KMS key is used to encrypt the secret. If the secret is in a different Amazon Web Services account, then you can’t use the aws/secretsmanager KMS key to encrypt the secret, and you must use a customer managed KMS key.
The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key. To use a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN.

There is a default KMS key for your Amazon Web Services account. Your Amazon Web Services account has a different default KMS key for each Amazon Web Services Region.

  For an Amazon Aurora DB cluster, this data type is used as a response element in the operations CreateDBCluster, DeleteDBCluster, DescribeDBClusters, FailoverDBCluster, ModifyDBCluster, PromoteReadReplicaDBCluster, RestoreDBClusterFromS3, RestoreDBClusterFromSnapshot, RestoreDBClusterToPointInTime, StartDBCluster, and StopDBCluster.
  
  For a Multi-AZ DB cluster, this data type is used as a response element in the operations CreateDBCluster, DeleteDBCluster, DescribeDBClusters, FailoverDBCluster, ModifyDBCluster, RebootDBCluster, RestoreDBClusterFromSnapshot, and RestoreDBClusterToPointInTime.
  
  For more information on Amazon Aurora DB clusters, see What is Amazon Aurora? in the Amazon Aurora User Guide.
  
  For more information on Multi-AZ DB clusters, see Multi-AZ deployments with two readable standby DB instances in the Amazon RDS User Guide.
  - AllocatedStorage (integer) –

  - PubliclyAccessible (boolean) –
    
    Indicates whether the DB cluster is publicly accessible.
    
    When the DB cluster is publicly accessible and you connect from outside of the DB cluster’s virtual private cloud (VPC), its Domain Name System (DNS) endpoint resolves to the public IP address. When you connect from within the same VPC as the DB cluster, the endpoint resolves to the private IP address. Access to the DB cluster is ultimately controlled by the security group it uses. That public access isn’t permitted if the security group assigned to the DB cluster doesn’t permit it.
    
    When the DB cluster isn’t publicly accessible, it is an internal DB cluster with a DNS name that resolves to a private IP address.

  - ServerlessV2ScalingConfiguration (dict) –
    
    The scaling configuration for an Aurora Serverless v2 DB cluster.
    
    For more information, see Using Amazon Aurora Serverless v2 in the Amazon Aurora User Guide.
    - MinCapacity (float) –
      
      The minimum number of Aurora capacity units (ACUs) for a DB instance in an Aurora Serverless v2 cluster. You can specify ACU values in half-step increments, such as 8, 8.5, 9, and so on. For Aurora versions that support the Aurora Serverless v2 auto-pause feature, the smallest value that you can use is 0. For versions that don’t support Aurora Serverless v2 auto-pause, the smallest value that you can use is 0.5.
    - MaxCapacity (float) –
      
      The maximum number of Aurora capacity units (ACUs) for a DB instance in an Aurora Serverless v2 cluster. You can specify ACU values in half-step increments, such as 32, 32.5, 33, and so on. The largest value that you can use is 256 for recent Aurora versions, or 128 for older versions.
    - SecondsUntilAutoPause (integer) –
      
      The number of seconds an Aurora Serverless v2 DB instance must be idle before Aurora attempts to automatically pause it. This property is only shown when the minimum capacity for the cluster is set to 0 ACUs. Changing the minimum capacity to a nonzero value removes this property. If you later change the minimum capacity back to 0 ACUs, this property is reset to its default value unless you specify it again.

    For more information, see Password management with Amazon Web Services Secrets Manager in the Amazon RDS User Guide and Password management with Amazon Web Services Secrets Manager in the Amazon Aurora User Guide.
    - SecretArn (string) –
      
      The Amazon Resource Name (ARN) of the secret.
    - SecretStatus (string) –
      
      The status of the secret.
      
      The possible status values include the following:

      - rotating - The secret is being rotated.
      - impaired - The secret can be used to access database credentials, but it can’t be rotated. A secret might have this status if, for example, permissions are changed so that RDS can no longer access either the secret or the KMS key for the secret. When a secret has this status, you can correct the condition that caused the status. Alternatively, modify the DB instance to turn off automatic management of database credentials, and then modify the DB instance again to turn on automatic management of database credentials.
    - KmsKeyId (string) –
      
      The Amazon Web Services KMS key identifier that is used to encrypt the secret.
