The ARN of the notification target that Auto Scaling will use to notify you when an instance is in the transition state for the lifecycle hook. This target can be either an SQS queue or an SNS topic. If you specify an empty string, this overrides the current ARN.
The notification messages sent to the target include the following information:
This operation uses the JSON format when sending notifications to an Amazon SQS queue, and an email key/value pair format when sending notifications to an Amazon SNS topic.
When you specify a notification target, Auto Scaling sends it a test
message. Test messages contains the following additional key/value pair:
"Event": "autoscaling:TEST_NOTIFICATION".
String notificationMetadata
Contains additional information that you want to include any time Auto Scaling sends a message to the notification target.
Integer heartbeatTimeout
The amount of time, in seconds, that can elapse before the lifecycle hook times out. When the lifecycle hook times out, Auto Scaling performs the default action. You can prevent the lifecycle hook from timing out by calling RecordLifecycleActionHeartbeat. The default is 3600 seconds (1 hour).

hook timeout elapses or if an unexpected failure occurs. This parameter
can be either CONTINUE or ABANDON. The default
value is ABANDON.
