Amazon Neptune uses Amazon Simple Notification Service (Amazon SNS) to provide notifications when a Neptune event occurs. These notifications can be in any form that is supported by Amazon SNS for an AWS Region, such as an email, a text message, or a call to an HTTP endpoint.
Neptune groups these events into categories that you can subscribe to so that you can be notified when an event in that category occurs. You can subscribe to an event category for a DB instance, DB cluster, DB snapshot, DB cluster snapshot, or for a DB parameter group. For example, if you subscribe to the Backup category for a given DB instance, you are notified whenever a backup-related event occurs that affects the DB instance. You also receive notification when an event notification subscription changes.
Events occur at both the DB cluster and the DB instance level, so you can receive events if you subscribe to a DB cluster or a DB instance.
Event notifications are sent to the addresses you provide when you create the subscription. You might want to create several different subscriptions, such as a subscription that receives all event notifications and another subscription that includes only critical events for your production DB instances. You can easily turn off notification without deleting a subscription. To do so, set the Enabled radio button to No in the Neptune console.
Important
Amazon Neptune doesn't guarantee the order of events sent in an event stream. The event order is subject to change.
Neptune uses the Amazon Resource Name (ARN) of an Amazon SNS topic to identify each subscription. The Neptune console creates the ARN for you when you create the subscription.
Billing for Neptune event notification is through Amazon SNS. Amazon SNS fees apply when using event
notification. For more information, see Amazon Simple Notification Service
