Explanation in CloudFormation Registry

The AWS::RDS::DBCluster resource creates an Amazon Aurora DB cluster. For more information, see Managing an Amazon Aurora DB Cluster in the Amazon Aurora User Guide.

Note You can only create this resource in AWS Regions where Amazon Aurora is supported.

Updating DB clustersWhen 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.

Important 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 about creating DB snapshots, 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 clustersThe default DeletionPolicy for AWS::RDS::DBCluster resources is Snapshot. For more information about how AWS CloudFormation deletes resources, see DeletionPolicy Attribute.
