// or the SNS API. To obtain an ARN with SNS, you must create a topic in Amazon
// SNS and subscribe to the topic. The ARN is displayed in the SNS console.
//
// You can specify the type of source (SourceType) you want to be notified of,
// provide a list of RDS sources (SourceIds) that triggers the events, and provide
// a list of event categories (EventCategories) for events 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 RDS sources. If you do not specify either the SourceType nor
// the SourceIdentifier, you are notified of events generated from all RDS sources
// belonging to your customer account.
