A CloudFormation AWS::RDS::DBCluster.

The AWS::RDS::DBCluster resource creates an Amazon Aurora DB cluster or Multi-AZ DB cluster.

For more information about creating an Aurora DB cluster, see Creating an Amazon Aurora DB cluster in the Amazon Aurora User Guide .

For more information about creating a Multi-AZ DB cluster, see Creating a Multi-AZ DB cluster in the Amazon RDS User Guide .

You can only create this resource in AWS Regions where Amazon Aurora or Multi-AZ DB clusters are supported.

Updating DB clusters

When properties labeled " Update requires: Replacement " are updated, AWS CloudFormation first creates a replacement DB cluster, then changes references from other dependent resources to point to the replacement DB cluster, and finally deletes the old DB cluster.

We highly recommend that you take a snapshot of the database before updating the stack. If you don't, you lose the data when AWS CloudFormation replaces your DB cluster. To preserve your data, perform the following procedure:

  • Deactivate any applications that are using the DB cluster so that there's no activity on the DB instance.
  • Create a snapshot of the DB cluster. For more information, see Creating a DB Cluster Snapshot .
  • If you want to restore your DB cluster using a DB cluster snapshot, modify the updated template with your DB cluster changes and add the SnapshotIdentifier property with the ID of the DB cluster snapshot that you want to use.

After you restore a DB cluster with a SnapshotIdentifier property, you must specify the same SnapshotIdentifier property for any future updates to the DB cluster. When you specify this property for an update, the DB cluster is not restored from the DB cluster snapshot again, and the data in the database is not changed. However, if you don't specify the SnapshotIdentifier property, an empty DB cluster is created, and the original DB cluster is deleted. If you specify a property that is different from the previous snapshot restore property, a new DB cluster is restored from the specified SnapshotIdentifier property, and the original DB cluster is deleted.

  • Update the stack.

Currently, when you are updating the stack for an Aurora Serverless DB cluster, you can't include changes to any other properties when you specify one of the following properties: PreferredBackupWindow , PreferredMaintenanceWindow , and Port . This limitation doesn't apply to provisioned DB clusters.

For more information about updating other properties of this resource, see [ModifyDBCluster](https://docs.aws.amazon.com//AmazonRDS/latest/APIReference/API_ModifyDBCluster.html) . For more information about updating stacks, see AWS CloudFormation Stacks Updates .

Deleting DB clusters

The default DeletionPolicy for AWS::RDS::DBCluster resources is Snapshot . For more information about how AWS CloudFormation deletes resources, see DeletionPolicy Attribute .

Valid for: Aurora DB clusters only


snapshotIdentifier?

Type: string (optional)

The identifier for the DB snapshot or DB cluster snapshot to restore from.

You can use either the name or the Amazon Resource Name (ARN) to specify a DB cluster snapshot. However, you can use only the ARN to specify a DB snapshot.

After you restore a DB cluster with a SnapshotIdentifier property, you must specify the same SnapshotIdentifier property for any future updates to the DB cluster. When you specify this property for an update, the DB cluster is not restored from the snapshot again, and the data in the database is not changed. However, if you don't specify the SnapshotIdentifier property, an empty DB cluster is created, and the original DB cluster is deleted. If you specify a property that is different from the previous snapshot restore property, a new DB cluster is restored from the specified SnapshotIdentifier property, and the original DB cluster is deleted.

If you specify the SnapshotIdentifier property to restore a DB cluster (as opposed to specifying it for DB cluster updates), then don't specify the following properties:

  • GlobalClusterIdentifier
  • MasterUsername
  • MasterUserPassword
  • ReplicationSourceIdentifier
  • RestoreType
  • SourceDBClusterIdentifier
  • SourceRegion
  • StorageEncrypted (for an encrypted snapshot)
  • UseLatestRestorableTime

Constraints:

  • Must match the identifier of an existing Snapshot.

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

sourceRegion?

Type: string (optional)

The AWS Region which contains the source DB cluster when replicating a DB cluster. For example, us-east-1 .

Valid for: Aurora DB clusters only


storageEncrypted?

Type: boolean | IResolvable (optional)

Indicates whether the DB cluster is encrypted.

If you specify the KmsKeyId property, then you must enable encryption.

If you specify the SourceDBClusterIdentifier property, don't specify this property. The value is inherited from the source DB cluster, and if the DB cluster is encrypted, the specified KmsKeyId property is used.

If you specify the SnapshotIdentifier and the specified snapshot is encrypted, don't specify this property. The value is inherited from the snapshot, and the specified KmsKeyId property is used.

If you specify the SnapshotIdentifier and the specified snapshot isn't encrypted, you can use this property to specify that the restored DB cluster is encrypted. Specify the KmsKeyId property for the KMS key to use for encryption. If you don't want the restored DB cluster to be encrypted, then don't set this property or set it to false .

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


storageType?

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


scalingConfiguration?

Type: IResolvable | ScalingConfigurationProperty (optional)

The ScalingConfiguration property type specifies the scaling configuration of an Aurora Serverless DB cluster.

This property is only supported for Aurora Serverless v1. For Aurora Serverless v2, use ServerlessV2ScalingConfiguration property.

Valid for: Aurora DB clusters only


serverlessV2ScalingConfiguration?

Type: IResolvable | ServerlessV2ScalingConfigurationProperty (optional)

The ServerlessV2ScalingConfiguration property type specifies the scaling configuration of an Aurora Serverless V2 DB cluster.

This property is only supported for Aurora Serverless v2. For Aurora Serverless v1, use ScalingConfiguration property.

Valid for: Aurora DB clusters only


snapshotIdentifier?

Type: string (optional)

The identifier for the DB snapshot or DB cluster snapshot to restore from.

You can use either the name or the Amazon Resource Name (ARN) to specify a DB cluster snapshot. However, you can use only the ARN to specify a DB snapshot.

After you restore a DB cluster with a SnapshotIdentifier property, you must specify the same SnapshotIdentifier property for any future updates to the DB cluster. When you specify this property for an update, the DB cluster is not restored from the snapshot again, and the data in the database is not changed. However, if you don't specify the SnapshotIdentifier property, an empty DB cluster is created, and the original DB cluster is deleted. If you specify a property that is different from the previous snapshot restore property, a new DB cluster is restored from the specified SnapshotIdentifier property, and the original DB cluster is deleted.

If you specify the SnapshotIdentifier property to restore a DB cluster (as opposed to specifying it for DB cluster updates), then don't specify the following properties:

  • GlobalClusterIdentifier
  • MasterUsername
  • MasterUserPassword
  • ReplicationSourceIdentifier
  • RestoreType
  • SourceDBClusterIdentifier
  • SourceRegion
  • StorageEncrypted (for an encrypted snapshot)
  • UseLatestRestorableTime

Constraints:

  • Must match the identifier of an existing Snapshot.

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


sourceDbClusterIdentifier?

Type: string (optional)

When restoring a DB cluster to a point in time, the identifier of the source DB cluster from which to restore.

Constraints:

  • Must match the identifier of an existing DBCluster.

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


sourceRegion?

Type: string (optional)

The AWS Region which contains the source DB cluster when replicating a DB cluster. For example, us-east-1 .

Valid for: Aurora DB clusters only


storageEncrypted?

Type: boolean | IResolvable (optional)

Indicates whether the DB cluster is encrypted.

If you specify the KmsKeyId property, then you must enable encryption.

If you specify the SourceDBClusterIdentifier property, don't specify this property. The value is inherited from the source DB cluster, and if the DB cluster is encrypted, the specified KmsKeyId property is used.

If you specify the SnapshotIdentifier and the specified snapshot is encrypted, don't specify this property. The value is inherited from the snapshot, and the specified KmsKeyId property is used.

If you specify the SnapshotIdentifier and the specified snapshot isn't encrypted, you can use this property to specify that the restored DB cluster is encrypted. Specify the KmsKeyId property for the KMS key to use for encryption. If you don't want the restored DB cluster to be encrypted, then don't set this property or set it to false .

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


storageType?

Type: string (optional)

The storage type to associate with the DB cluster.

For information on storage types for Aurora DB clusters, see Storage configurations for Amazon Aurora DB clusters . For information on storage types for Multi-AZ DB clusters, see Settings for creating Multi-AZ DB clusters .

This setting is required to create a Multi-AZ DB cluster.

When specified for a Multi-AZ DB cluster, a value for the Iops parameter is required.

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

Valid Values:

  • Aurora DB clusters - aurora | aurora-iopt1
  • Multi-AZ DB clusters - io1

Default:

  • Aurora DB clusters - aurora
  • Multi-AZ DB clusters - io1

useLatestRestorableTime?

Type: boolean | IResolvable (optional)

A value that indicates whether to restore the DB cluster to the latest restorable backup time.

By default, the DB cluster is not restored to the latest restorable backup time.

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


vpcSecurityGroupIds?

Type: string[] (optional)

A list of EC2 VPC security groups to associate with this DB cluster.

If you plan to update the resource, don't specify VPC security groups in a shared VPC.

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

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

  • path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).


addDependency(target)

public addDependency(target: CfnResource): void

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.


addDependsOn(target)⚠️

public addDependsOn(target: CfnResource): void

⚠️ Deprecated: use addDependency

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.


addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

  • key string
  • value any

Add a value to the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)


addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

  • path string — - The path of the property, you can use dot notation to override values in complex types.
  • value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.


addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

  • propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.


addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

  • propertyPath string — The path of the property.
  • value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).


applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

  • policy RemovalPolicy
  • options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

Parameters

  • attributeName string — The name of the attribute.
  • typeHint ResolutionTypeHint

Returns

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.


getMetadata(key)

public getMetadata(key: string): any

Parameters

  • key string

Returns

  • any

Retrieve a value value from the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)
