-- Creates an AWS DMS event notification subscription.
--
--
-- You can specify the type of source (@SourceType@ ) you want to be notified of, provide a list of AWS DMS source IDs (@SourceIds@ ) that triggers the events, and provide a list of event categories (@EventCategories@ ) for events you want to be notified of. If you specify both the @SourceType@ and @SourceIds@ , such as @SourceType = replication-instance@ and @SourceIdentifier = my-replinstance@ , you will be notified of all the replication instance events for the specified source. If you specify a @SourceType@ but don't specify a @SourceIdentifier@ , you receive notice of the events for that source type for all your AWS DMS sources. If you don't specify either @SourceType@ nor @SourceIdentifier@ , you will be notified of events generated from all AWS DMS sources belonging to your customer account.

-- | Creates a value of 'CreateEventSubscription' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'cesEnabled' - A Boolean value; set to __true__ to activate the subscription, or set to __false__ to create the subscription but not activate it.
--
-- * 'cesSourceType' - The type of AWS DMS resource that generates the events. For example, if you want to be notified of events generated by a replication instance, you set this parameter to @replication-instance@ . If this value is not specified, all events are returned.  Valid values: replication-instance | migration-task
--
-- * 'cesEventCategories' - A list of event categories for a source type that you want to subscribe to. You can see a list of the categories for a given source type by calling the __DescribeEventCategories__ action or in the topic <http://docs.aws.amazon.com/dms/latest/userguide/CHAP_Events.html Working with Events and Notifications> in the AWS Database Migration Service User Guide.
--
-- * 'cesSourceIds' - The list of identifiers of the event sources for which events will be returned. If not specified, then all sources are included in the response. An identifier must begin with a letter and must contain only ASCII letters, digits, and hyphens; it cannot end with a hyphen or contain two consecutive hyphens.
--
-- * 'cesTags' - A tag to be attached to the event subscription.
--
-- * 'cesSubscriptionName' - The name of the AWS DMS event notification subscription.  Constraints: The name must be less than 255 characters.
--
-- * 'cesSNSTopicARN' - The Amazon Resource Name (ARN) of the Amazon SNS topic created for event notification. The ARN is created by Amazon SNS when you create a topic and subscribe to it.
