Creating an Event Hub in Azure Event Hubs
This tutorial guides you through the process of creating a new Event Hub within an Azure Event Hubs namespace. Event Hubs is a highly scalable data streaming platform and event ingestion service that can receive and process millions of events per second.
Prerequisites
- An Azure subscription. If you don't have one, create a free account before you begin.
- An existing Azure Event Hubs namespace. If you need to create one, please refer to this guide.
Steps to Create an Event Hub
1. Navigate to your Event Hubs Namespace
- Log in to the Azure portal.
- In the search bar at the top, type Event Hubs and select Event Hubs from the search results.
- Select your existing Event Hubs namespace from the list.
2. Initiate Event Hub Creation
- On the overview page of your Event Hubs namespace, click the + Event Hub button in the toolbar.
3. Configure Event Hub Settings
A panel will appear on the right side of the screen to configure the new Event Hub.
- Name: Enter a unique name for your Event Hub. This name must be between 1 and 50 characters and can contain only letters, numbers, periods (.), underscores (_), and hyphens (-).
- Partition Count: This setting determines the number of partitions for your Event Hub. Partitions are ordered sequences of events. A higher partition count can increase throughput. For most scenarios, starting with 2-4 partitions is common.
- Message Retention: Specify how long events should be retained in the Event Hub. The default is 1 day, but you can set it up to 7 days.
Understanding Partitions
The partition count impacts the parallelism of event processing. Consumers can read from partitions in parallel. Choose a partition count that aligns with your expected event throughput and processing capabilities.
4. Create the Event Hub
- After filling in the required details, click the Create button at the bottom of the panel.
The Azure portal will begin creating your Event Hub. This process usually takes a few moments. You'll see a notification in the portal indicating the deployment status.
5. Verify Event Hub Creation
- Once the creation is complete, you should see your newly created Event Hub listed under the Event Hubs section of your namespace's overview page.
Congratulations! You have successfully created an Event Hub. You can now configure applications or services to send events to and receive events from this Event Hub.
