Request Parameters Response Elements Errors See Also

CreateEventSubscription

Creates an Amazon DocumentDB event notification subscription. This action requires a topic Amazon Resource Name (ARN) created by using the Amazon DocumentDB console, the Amazon SNS console, or the Amazon SNS API. To obtain an ARN with Amazon SNS, you must create a topic in Amazon SNS and subscribe to the topic. The ARN is displayed in the Amazon SNS console.

You can specify the type of source (SourceType) that you want to be notified of. You can also provide a list of Amazon DocumentDB sources (SourceIds) that trigger the events, and you can provide a list of event categories (EventCategories) for events that you want to be notified of. For example, you can specify SourceType = db-instance, SourceIds = mydbinstance1, mydbinstance2 and EventCategories = Availability, Backup.

If you specify both the SourceType and SourceIds (such as SourceType = db-instance and SourceIdentifier = myDBInstance1), you are notified of all the db-instance events for the specified source. If you specify a SourceType but do not specify a SourceIdentifier, you receive notice of the events for that source type for all your Amazon DocumentDB sources. If you do not specify either the SourceType or the SourceIdentifier, you are notified of events generated from all Amazon DocumentDB sources belonging to your customer account.
