'How to get a notification when there is a new message in an Azure Service Bus queue?
I understand that we have Azure Service Bus trigger for Azure Functions:
https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-service-bus-trigger
I need to get a “Service Bus New Message” notification in my application that is not hosted in Azure Functions. I don’t want to limit my application hosting options to Azure Functions only.
Questions:
How can I get a notification when there is a new message in an Azure Service Bus queue?
What is the notification protocol/mechanism between Service Bus and Azure Function so the we have the Service Bus Trigger feature in Azure Functions?
Solution 1:[1]
The trigger uses either a ServiceBusProcessor or ServiceBusReceiver in the background, depending on the configuration. These are responsible for polling the queue/subscription. (ref)
Unfortunately, I don't know of another way to be notified for a standard namespace. If you're using a premium Service Bus namespace, there is integration with Event Grid that can alert you when a message is available and there is no active receiver. Details can be found in the Azure Service Bus to Event Grid integration overview.
