--
-- 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 Amazon Web
-- Services 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 Amazon Web Services account.
-- You must specify a source type if you specify a source ID.
