The time-to-live expiration is checked ONLY at the next scheduled delivery attempt. Webhook Event delivery. This article describes how Azure Event Grid handles events when delivery isn't acknowledged. Azure Event Grid is a highly scalable event-routing service that listens for specific system events, then reacts to them according to your precise specifications.In the past, event handling has relied largely on polling—a high latency, low-efficiency approach that can prove prohibitively expensive at scale. Event Grid uses HTTP response codes to acknowledge receipt of events. Azure Event Grid is an awesome new service in Azure that connects applications together through event messaging. - [Instructor] Let's start by understanding the basics of what is the Azure Event Grid. Note, you have to install an eventgrid extension . All other status codes are considered failed deliveries and will be retried or deadlettered as appropriate. Many times, one microservice might need to queryanother, requiring an immediate response to complete an operation. Alternatively, you can use Event Grid with Logic Apps to process data anywhere, without writing code. Le point de terminaison se présente sous la forme suivante : Vous souhaiterez peut-être être averti lorsqu’un événement a été envoyé à l’emplacement des lettres mortes. Stockage Blob AzureAzure Blob Storage 3. The subscriber receives an array with a single event. These response codes indicate delivery of the event will never succeed. Avant de définir l’emplacement des lettres mortes, vous devez disposer d’un compte de stockage avec un conteneur. When Event Grid can't deliver an event within a certain time period or after trying to deliver the event a certain number of times, it can send the undelivered event to a storage account. If a registered subscription listener does not acknowledge the event emitted through Event Grid, Event Grid will try to deliver the event again.

Après 30 secondes, si le point de terminaison n’a pas répondu, le message est mis en file d’attente en vue d’une nouvelle tentative.After 30 seconds, if the endpoint hasn’t responded, the message is queued for retry.

Vous pouvez personnaliser la stratégie de nouvelle tentative lors de la création d’un abonnement à un événement.You can customize the retry policy when creating an event subscription. Si l’une des conditions est remplie, l’événement est abandonné ou mis en file d’attente de lettres mortes.If either of the conditions is met, the event is dropped or dead-lettered.

Series There is a five-minute delay between the last attempt to deliver an event and when it is delivered to the dead-letter location. Pour un comportement déterministe, définissez la durée de l’événement de durée de vie et de nombre maximum de tentatives de remise dans les stratégies de nouvelle tentative d’abonnement.For deterministic behavior, set the event time to live and max delivery attempts in the subscription retry policies. Any event that cannot be delivered to its' destination is sent to the dead letter destination. Event Grid uses an exponential backoff retry policy for event delivery. Par conséquent, même si la durée de vie expire avant la prochaine tentative de livraison planifiée, l’expiration de l’événement est vérifiée uniquement au moment de la prochaine livraison, puis devient lettre morte par la suite.Therefore, even if time-to-live expires before the next scheduled delivery attempt, event expiry is checked only at the time of the next delivery and then subsequently dead-lettered.

Par exemple, si les dix premiers événements publiés sur un point de terminaison échouent, Event Grid supposera que le point de terminaison rencontre des problèmes et retardera toutes les tentatives suivantes, For example, if the first 10 events published to an endpoint fail, Event Grid will assume that the endpoint is experiencing issues and will delay all subsequent retries.
