#ServerlessTips - Azure Event Grid
Author: Steef-Jan Wiggers Azure MVP

On each subscription in Event Grid, you can manage the filters (Event Type, Subject, and Advanced) and configure a few additional features such as retry policies, dead-lettering, and event subscription expiration. These other features are accessible in each subscription in the features tab.

Event Grid guarantees at least one delivery of the event to a subscriber.

When the subscriber cannot accept an event – the Event Grid by default will retry for 24 hours to deliver the event through an exponential backoff mechanism.

However, you can manipulate the retries and time to live of an event in retry policies part of the features.

In the same features tab, you can also enable dead lettering for the event. When an event cannot be delivered according to the retry policy, it can be stored in a container of a storage account of your choice.

Lastly, you can manage expiration time for a subscription, which means you can set a date time for when the subscription for the event should be terminated.

These features can enhance your subscription besides the filter options – thus creating a more sophisticated subscription for the event handling services.
