Azure Functions Bindings & Triggers - EventHubs

This page provides an overview of EventHub triggers and bindings within Azure Functions.

What are EventHubs?

EventHubs are a scalable event ingestion service for collecting telemetry data from millions of devices and applications. They're a key component in building real-time data processing pipelines.

EventHub Trigger in Azure Functions

The EventHub trigger allows your Azure Function to receive events from an EventHub. This is useful for scenarios like:

• Processing IoT device telemetry
• Real-time analytics
• Data streaming

Bindings

Bindings define how your function interacts with the EventHub. You'll typically use the `EventHubTrigger` binding.

Example Code Snippet

`[FunctionName("MyFunction")]
public static async Task MyFunction([EventHubTrigger("myhub", Connection="MyConnection")] string message)
{
    // Process the message
    Console.WriteLine(message);
}
`
            

Key parts of the binding:

• `myhub`: The name of your EventHub.
• `Connection`: The connection string to your EventHub.
