What are Event Hubs Bindings?
Event Hubs bindings allow you to consume events directly from an Event Hubs namespace within your Azure Function. This enables real-time processing of data streams without requiring traditional polling or long-running processes.
Key Concepts
- Event Hubs Namespace: A logical grouping of Event Hubs that allows you to organize and manage events.
- Event Hubs: A fully managed, real-time event ingestion service.
- Bindings: Declarative configuration elements in your function code that connect to Event Hubs.
- Partitions: Event Hubs is horizontally scalable. Events are distributed across multiple partitions.
- Throughput: Event Hubs is designed for high-throughput event processing.
Getting Started
To begin, you'll need an active Azure subscription and an Event Hubs namespace. The following steps outline the basic workflow:
- Create an Event Hubs Namespace: Use the Azure portal or Azure CLI to create a new Event Hubs namespace.
- Create an Event Hub: Within the namespace, create an Event Hub to capture your events.
- Create an Azure Function: Develop an Azure Function with an Event Hubs binding.
- Configure the Binding: Specify the Event Hub name and any other relevant settings in the binding configuration.
- Test the Function: Send events to the Event Hub and verify that your function processes them correctly.
