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

Type: String

Required: No

EngineVersion

The version number of the database engine to which you want to upgrade. Changing this parameter results in an outage. The change is applied during the next maintenance window unless ApplyImmediately is enabled.

ManageMasterUserPassword

Specifies whether to manage the master user password with AWS Secrets Manager.

If the DB cluster already manages the master user password with AWS Secrets Manager, and you specify that the master user password is not managed with AWS Secrets Manager, then you must specify MasterUserPassword. In this case, RDS deletes the secret and uses the new password for the master user specified by MasterUserPassword.

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

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

MasterUserSecretKmsKeyId

The AWS KMS key identifier to encrypt a secret that is automatically generated and managed in AWS 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 AWS Secrets Manager.

If the DB cluster already manages the master user password in AWS 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 AWS 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 AWS 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 AWS 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 AWS account, specify the key ARN or alias ARN.

There is a default KMS key for your AWS account. Your AWS account has a different default KMS key for each AWS Region.
