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
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

metrics are collected for the DB cluster. To turn off collecting
Enhanced Monitoring metrics, specify 0.
If MonitoringRoleArn is specified, also set MonitoringInterval to a
value other than 0.
Valid for Cluster Type: Multi-AZ DB clusters only
Valid Values: 0 | 1 | 5 | 10 | 15 | 30 | 60
Default: 0
The Amazon Resource Name (ARN) for the IAM role that permits RDS to send
Enhanced Monitoring metrics to Amazon CloudWatch Logs. An example is
arn:aws:iam:123456789012:role/emaccess. For information on creating a
monitoring role, see To create an IAM role for Amazon RDS Enhanced Monitoring
in the Amazon RDS User Guide.
If MonitoringInterval is set to a value other than 0, supply a
MonitoringRoleArn value.
Valid for Cluster Type: Multi-AZ DB clusters only
Specifies whether to turn on Performance Insights for the DB cluster.
For more information, see Using Amazon Performance Insights in the Amazon RDS User Guide.
Valid for Cluster Type: Multi-AZ DB clusters only
The Amazon Web Services KMS key identifier for encryption of Performance Insights data.
The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key.
If you don't specify a value for PerformanceInsightsKMSKeyId, then
Amazon RDS uses your default KMS key. 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.
Valid for Cluster Type: Multi-AZ DB clusters only
The number of days to retain Performance Insights data.
Valid for Cluster Type: Multi-AZ DB clusters only
Valid Values:
7
month * 31, where month is a number of months from 1-23.
Examples: 93 (3 months * 31), 341 (11 months * 31), 589 (19
months * 31)
731
Default: 7 days
If you specify a retention period that isn't valid, such as 94, Amazon
RDS issues an error.
The network type of the DB cluster.
The network type is determined by the DBSubnetGroup specified for the
DB cluster. A DBSubnetGroup can support only the IPv4 protocol or the
IPv4 and the IPv6 protocols (DUAL).
For more information, see Working with a DB instance in a VPC in the Amazon Aurora User Guide.
Valid for Cluster Type: Aurora DB clusters only
Valid Values: IPV4 | DUAL
Specifies whether to manage the master user password with Amazon Web Services Secrets Manager.
If the DB cluster doesn't manage the master user password with Amazon
Web Services Secrets Manager, you can turn on this management. In this
case, you can't specify MasterUserPassword.
If the DB cluster already manages the master user password with Amazon
Web Services Secrets Manager, and you specify that the master user
password is not managed with Amazon Web Services 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 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
Specifies whether to rotate the secret managed by Amazon Web Services Secrets Manager for the master user password.
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.
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.
Valid for Cluster Type: Aurora DB clusters and Multi-AZ DB clusters
