Azure Service Bus now integrates with Azure Event Grid!

We are happy to announce that Azure Service Bus is now able to send events to Azure Event Grid. The key scenario this feature enables is that Service Bus Queues or Topics / Subscriptions that have a very low volume of messages, do not have to have a receiver polling for messages at all times. Service Bus will now send events to Azure Event Grid when there are messages in a Queue or Topics / Subscriptions if no receivers are present. You can create Azure Event Grid subscriptions for your Service Bus namespaces and listen to these events and react to the events by starting a receiver. With this feature, Service Bus can be used in reactive programming models.

In the current release, this feature is for Premium namespaces only and is only available in regions where Event Grid is available. We will add support for Standard Namespaces at a later point in time.

Known issues:

  1. Right now Azure Event Grid does not support multiple filters per subscription. This is a feature we are currently working on. To work around this, you can simply create multiple Event Grid Subscriptions.
  2. Additionally Logic Apps right now has no straight forward way of closing the connection once it received, hence Service Bus will emit events only every 10 minutes as it waits for the idle timeout of the connection.
  3. Right now you will need to use a Http Trigger Azure function. The Service Bus enabled Azure Functions do not support Event Grid yet.
