@Stability(Stable) public static interface CfnBucketPropsMixin.NotificationConfigurationProperty extends software.amazon.jsii.JsiiSerializable
Describes the notification configuration for an Amazon S3 bucket.

If you create the target resource and related permissions in the same template, you might have a circular dependency.

For example, you might use the AWS::Lambda::Permission resource to grant the bucket permission to invoke an AWS Lambda function. However, AWS CloudFormation can't create the bucket until the bucket has permission to invoke the function ( AWS CloudFormation checks whether the bucket can invoke the function). If you're using Refs to pass the bucket name, this leads to a circular dependency.

To avoid this dependency, you can create all resources without specifying the notification configuration. Then, update the stack with a notification configuration.

For more information on permissions, see AWS::Lambda::Permission and Granting Permissions to Publish Event Notification Messages to a Destination .
