--
-- 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.
