Bases: CfnResource

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 . .. epigraph:

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. .. epigraph:

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 <https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_CreateSnapshotCluster.html>`_ .
- 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 .

Constraints: Minimum 30-minute window. Valid for: Aurora DB clusters and Multi-AZ DB clusters
publicly_accessible (Union[bool, IResolvable, None]) – A value that indicates whether the DB cluster is publicly accessible. When the DB cluster is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB cluster’s virtual private cloud (VPC). It resolves to the public IP address from outside of the DB cluster’s VPC. 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. Default: The default behavior varies depending on whether DBSubnetGroupName is specified. If DBSubnetGroupName isn’t specified, and PubliclyAccessible isn’t specified, the following applies: - If the default VPC in the target Region doesn’t have an internet gateway attached to it, the DB cluster is private. - If the default VPC in the target Region has an internet gateway attached to it, the DB cluster is public. If DBSubnetGroupName is specified, and PubliclyAccessible isn’t specified, the following applies: - If the subnets are part of a VPC that doesn’t have an internet gateway attached to it, the DB cluster is private. - If the subnets are part of a VPC that has an internet gateway attached to it, the DB cluster is public.

This property is only supported for Aurora Serverless v2. For Aurora Serverless v1, use ScalingConfiguration property. Valid for: Aurora DB clusters only
snapshot_identifier (Optional[str]) – 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.

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
storage_type (Optional[str]) – Specifies the storage type to be associated with the DB cluster. This setting is required to create a Multi-AZ DB cluster.

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.

Parameters:

target (CfnResource) –

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

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.

add_override(path, 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:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"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.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

snapshot_identifier

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

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 .
