In two previous blog posts, I explained how to create a Kafka consumer and producer with the Spring Cloud Stream framework. In the Famous Last Words section of the producer, I already hinted at the notion of utilizing this technology for connecting to Azure Event Hub. While doing so, I discovered an error in one of Microsoft’s examples that has cost me about two days of work. I show you how to avoid the dreaded “Node -1 disconnected” error.

In this tutorial, I explain how to use the exact same code to connect to Azure Event Hub using a Shared Access Signature Token (connection string) and a Service Principal.

I have good news and bad news. Which one first? The bad? Okay, here we go:

There will not be any code in this tutorial, only YAML configuration.

Now to the good part:

There will not be any code in this tutorial, only YAML configuration.

This is the beauty of Spring Cloud Stream. Granted, I am not even swapping the binder for an Azure-native variant. So why would there be any code changes? But let me say this: I briefly plugged in the Event Hub Binder without changing the code in my research on getting this to work. Even the updates to the config were minimal. A few Event Hub-specific settings, especially the Storage Account for checkpoints, and that was it.

Enough foreplay; let me explain what you likely came here for.
