Creates an RDS event notification subscription. This action requires a topic ARN (Amazon Resource Name) created by either the RDS console, the SNS console, 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 will be notified of all the db-instance events for the specified source. If you specify a SourceType but do not specify a SourceIdentifier, you will 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 will be notified of events generated from all RDS sources belonging to your customer account.
Required arguments:
 -sns_topic_arn        The Amazon Resource Name (ARN) of the SNS topic created
                       for event notification. The ARN is created by Amazon SNS
                       when you create a topic and subscribe to it.
 -subscription_name    The name of the subscription.
Optional arguments:
 -enabled              Boolean; set to true to activate the subscription, set to
                       false to create the subscription but not active it.

                                       with the specified option group.  Changing this parameter does
                                       not result in an outage except in the following case and the
                                       change is applied during the next maintenance window unless the
                                       -apply_immediately argument is set to true for this request. If
                                       the parameter change results in an option group that enables OEM,
                                       this change can cause a brief (sub-second) period during which
                                       new connections are rejected but existing connections are not
                                       interrupted.
                                       Note that persistent options, such as the TDE_SQLServer option for
                                       Microsoft SQL Server, cannot be removed from an option group while
                                       DB instances are associated with the option group. Permanent options,
                                       such as the TDE option for Oracle Advanced Security TDE, cannot be
                                       removed from an option group, and that option group cannot be removed
                                       from a DB instance once it is associated with a DB instance.
