We are happy to share that Azure Service Bus is now able to send events to Azure Event Grid. The key scenario this feature enables is for Service Bus queues, topics, or subscriptions with low message volumes to not require a receiver to be polling for messages at all times. Service Bus will now send events to Azure Event Grid when there are messages in a queue if no receivers are present. You can create Azure Event Grid subscriptions for your Service Bus namespaces, 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.
Today, Azure Service Bus sends events for two scenarios:
- Active messages with no listeners available
- Deadletter messages available
