Can we make custom events for future in Azure Event Grid ?

Koushik Purva Mahendra 25

Hello Microsoft,

My question is that can I make custom events in azure Event Grid to trigger my azure function in coming future, for example can I make a Event in Azure event grid to get trigger my azure function tomorrow or day after tomorrow or after 10 days, is it possible that I have to trigger my azure function for next 60 days daily at a specific time so I can make straight 60 Custom events in azure event grid for a specific time and now that each event will trigger my azure function at specific date and time I given to the event.

Please clear my concern as this is on priority basis for me.

Thanks.

@Koushik Purva Mahendra Thanks for reaching out. Unfortunately, you cannot schedule the events for the future date in the event grid. The alternative will be using the Service Bus to schedule the message by specifying the ScheduledEnqueueTimeUtc property on the message before sending it. Based on the schedule time the message will be visible in the queue to be consumed and your function app with service bus trigger can consume those messages. For more details, please refer to this document.

Feel free to get back to me if you have any queries or concerns.

Hi @Koushik Purva Mahendra ,

Your requirement such as delaying of the event delivery in the AEG can be achieved without coding using an Azure Service Bus Topic entity with ForwardTo feature and Rule Action for setting a message sys properties (such as sys.ScheduledEnqueueTimeUtc, sys.Label, etc.). The following picture shows this solution:

The Delay value can be configured in the Delivery Properties of the Event Subscription (statically or dynamically from the event) and used it in the Rule Action. As a destination resource can be used a Service Bus Queue or Topic based on your needs.

Thanks

Just to add that only the listed property as currently supported and ScheduledEnqueueTimeUtc is not the property that is supported currently as per the document.

Hello @MayankBargali-MSFT So it means as ScheduledEnqueueTimeUtc is not supported yet, I can't schedule the messages to appear in the Service Bus Queue for the coming future for example I want to schedule a message today to be appear in queue for tomorrow or after one week, this thing is not supported yet ?

@Koushik Purva Mahendra It is respect to the comment posted by Roman that the event grid subscription to service bus as desination endpoint that it doesn't support setting the ScheduledEnqueueTimeUtc property as documented here.

As I mentioned previously with event grid it is not possible but using custom code with service bus it is possible by leveraging ScheduledEnqueueTimeUtc property on the message before sending it.

@MayankBargali-MSFT I got it, currently I am trying to do it using Go language as soon as I'll get positive response to this, I'll accept this answer, you can share me other DOC links if you have that can help do this with Go language, Thank you.

Hi @MayankBargali-MSFT ,

Based on my working solution, the destination resource for AEG event is the Azure Service Bus Topic which is a forwarder to the final delayed resource such as Service Queue or Topic.

Note, that the AEG delivery properties is used for passing a delay value to the user property of the Service Bus Topic message and use it in its Rule Action for setup a message delay:

SET sys.ScheduledEnqueueTimeUtc = delay;

Thanks

Roman Kiss Thanks for your response. If this works now, then this would be a document bug. Let me test it at my end and will update the document if the ScheduledEnqueueTimeUtc is now supported. Apology for the connfusion.

@MayankBargali-MSFT , The listed delivery properties for Service Bus entity in the AEG Subscription is correct.

The key to my mentioned solution is to use the Service Bus Topic as the AEG destination resource, because this resource has a capability to handle a Rule Action in its subscription, so that's the place, where we can setup the ScheduledEnqueueTimeUtc property.

Note, that the destination resource Service Bus Topic in this solution is the forwarder of the event message, so its forwardTo property must be setup to the final delayed Service Bus Queue or Topic.

Basically, this solution uses two Service Bus entities, the first one must be a Service Bus Topic, such as a destination of the AEG event message and also it is a forwarder of delayed message to the second Service Bus entity.

Thanks
