Reading Azure Service Bus Queue

Question

I\'m simply trying to work out how best to retrieve messages as quickly as possible from an Azure Service Bus Queue.

I was shocked that there wasn\'t some way to pr

Answer 1

To deal with Azure ServiceBus Queue easily, the best option seems to be Azure Webjob.

There is a ServiceBusTrigger that allows you to get messages from an Azure ServiceBus queue.

For node.js integration, you should have a look at Azure Function. It is built on top of the webjob SDK and have node.js integration :

• Azure Functions NodeJS developer reference
• Azure Functions Service Bus triggers and bindings for queues and topics

In the second article, there is an example on how get messages from a queue using Azure Function and nodejs :

module.exports = function(context, myQueueItem) {
    context.log('Node.js ServiceBus queue trigger function processed message', myQueueItem);
    context.done();
};

Check out these videos from Scott Hanselman and Mark Simms on Azure Queues. It's C# but you get the idea.

Touches on:

• Storage Queues vs. Service Bus Queues
• Grabbing messages in bulk vs. one by one (chunky vs. chatty)
• Dealing with poison messages (bad actors)
• Misc implementation details
• Much more stuff i can't remember now

As for your compute, you can either do a VM, a Worker Role (Cloud Services), App Service Webjobs, or Azure Functions.

The Webjobs SDK and Azure Functions bot have a way to subscribe to Queue events (notify on message).

(Listed from IaaS to PaaS to FaaS - Azure Functions - if such a thing exists).

Azure Functions already has sample code provided as templates to do all that with Node. Just make a new Function and follow the wizard.

If you need to touch data on-prem you either need to look at integrating with a VNET that has site-to-site connectivity back to your prem, or Hybrid Connections (App Service only!). Azure Functions can't do that yet, but every other compute is a go.
