// CreateEventSubscriptionRequest returns a request value for making API operation for

//
// Creates an Amazon Redshift event notification subscription. This action requires
// an ARN (Amazon Resource Name) of an Amazon SNS topic created by either the
// Amazon Redshift 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 SNS console.
//
// You can specify the source type, and lists of Amazon Redshift source IDs,
// event categories, and event severities. Notifications will be sent for all
// events you want that match those criteria. For example, you can specify source
// type = cluster, source ID = my-cluster-1 and mycluster2, event categories
// = Availability, Backup, and severity = ERROR. The subscription will only
// send notifications for those ERROR events in the Availability and Backup
// categories for the specified clusters.
//
// If you specify both the source type and source IDs, such as source type =
// cluster and source identifier = my-cluster-1, notifications will be sent
// for all the cluster events for my-cluster-1. If you specify a source type
// but do not specify a source identifier, you will receive notice of the events
// for the objects of that type in your AWS account. If you do not specify either
// the SourceType nor the SourceIdentifier, you will be notified of events generated
// from all Amazon Redshift sources belonging to your AWS account. You must
// specify a source type if you specify a source ID.
