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

Type: Boolean

Required: No

Domain

The Active Directory directory ID to move the DB cluster to. Specify none to remove the cluster from its current domain. The domain must be created prior to this operation.

For more information, see Kerberos Authentication in the Amazon Aurora User Guide.

EnableGlobalWriteForwarding

A value that indicates whether to enable this DB cluster to forward write operations to the primary cluster of an Aurora global database (GlobalCluster). By default, write operations are not allowed on Aurora DB clusters that are secondary clusters in an Aurora global database.

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 the FailoverGlobalCluster API operation, but it does nothing until then.

Valid for: Aurora DB clusters only

Type: Boolean

Required: No

EnableHttpEndpoint

A value that indicates whether to enable the HTTP endpoint for an Aurora Serverless v1 DB cluster. By default, the HTTP endpoint is disabled.

When enabled, the HTTP endpoint provides a connectionless web service API for running SQL queries on the Aurora Serverless v1 DB cluster. You can also query your database from inside the RDS console with the query editor.

For more information, see Using the Data API for Aurora Serverless v1 in the Amazon Aurora User Guide.

Valid for: Aurora DB clusters only

Type: Boolean

Required: No

Note

The DB engine mode can be modified only from serverless to provisioned.

For more information, see CreateDBCluster.

Valid for: 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.

If the cluster that you're modifying has one or more read replicas, all replicas must be running an engine version that's the same or later than the version you specify.

To list all of the available engine versions for Aurora MySQL, use the following command:

aws rds describe-db-engine-versions --engine aurora-mysql --query "DBEngineVersions[].EngineVersion"

To list all of the available engine versions for Aurora PostgreSQL, use the following command:

aws rds describe-db-engine-versions --engine aurora-postgresql --query "DBEngineVersions[].EngineVersion"

To list all of the available engine versions for RDS for MySQL, use the following command:

aws rds describe-db-engine-versions --engine mysql --query "DBEngineVersions[].EngineVersion"

To list all of the available engine versions for RDS for PostgreSQL, use the following command:

aws rds describe-db-engine-versions --engine postgres --query "DBEngineVersions[].EngineVersion"

Valid for: Multi-AZ DB clusters only

Type: Integer

Required: No

ManageMasterUserPassword

A value that indicates whether to manage the master user password with AWS Secrets Manager.

If the DB cluster doesn't manage the master user password with AWS 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 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: Aurora DB clusters and Multi-AZ DB clusters

Type: Boolean

Required: No

MasterUserPassword

The new password for the master database user. This password can contain any printable ASCII character except "/", """, or "@".

Constraints:

  • Must contain from 8 to 41 characters.

  • Can't be specified if ManageMasterUserPassword is turned on.

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

Type: String

Required: No

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.

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

Type: String

Required: No

MonitoringInterval

The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the DB cluster. To turn off collecting Enhanced Monitoring metrics, specify 0. The default is 0.

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: Multi-AZ DB clusters only

Type: String

Required: No

NetworkType

The network type of the DB cluster.

Valid values:

  • IPV4

  • DUAL

For more information, see Working with a DB instance in a VPC in the Amazon Aurora User Guide.

Valid for: Aurora DB clusters only

Type: String

Required: No

NewDBClusterIdentifier

The new DB cluster identifier for the DB cluster when renaming a DB cluster. This value is stored as a lowercase string.

The AWS KMS key identifier for encryption of Performance Insights data.

The AWS 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 AWS account. Your AWS account has a different default KMS key for each AWS Region.

For example, the following values are valid:

  • 93 (3 months * 31)

  • 341 (11 months * 31)

  • 589 (19 months * 31)

  • 731

If you specify a retention period such as 94, which isn't a valid value, RDS issues an error.

Valid for: Multi-AZ DB clusters only
