How to Manage Azure Event Hubs
This guide covers common operations for managing your Azure Event Hubs, including creating, updating, and deleting Event Hubs, as well as configuring their properties.
Prerequisites
- An Azure subscription.
- An Azure Event Hubs namespace created.
- Permissions to manage resources within your Event Hubs namespace.
Managing Event Hubs using the Azure Portal
The Azure portal provides a user-friendly interface for managing your Event Hubs.
- Navigate to your Event Hubs namespace in the Azure portal.
- In the left-hand menu, under "Entity Management", click on "Event Hubs".
- You will see a list of existing Event Hubs. You can click on an Event Hub to view and manage its specific settings.
Creating an Event Hub
To create a new Event Hub:
- Go to your Event Hubs namespace in the Azure portal.
- Click the "+ Event Hub" button.
- Enter a name for your Event Hub.
- Configure settings such as the number of partitions and message retention period.
- Click "Create".
Configuring Event Hub Properties
Once an Event Hub is created, you can modify its settings:
Message Retention
The message retention period determines how long Event Hubs retains data. This can be configured from 1 to 7 days.
Partitions
Partitions are a fundamental concept for scaling Event Hubs. You can increase the number of partitions up to the maximum allowed for your tier. Decreasing partitions is not supported after creation.
# Example: Increasing partitions (conceptually, done via portal/API)
# Note: This operation might require a brief interruption or careful planning.
# Always check Azure documentation for the exact procedure and limitations.
Managing Event Hubs using Azure CLI
You can also manage Event Hubs programmatically using the Azure CLI.
Create an Event Hub
az eventhubs event-hub create --name \
--namespace-name \
--resource-group \
--partition-count \
--message-retention
List Event Hubs
az eventhubs event-hub list --namespace-name \
--resource-group
Delete an Event Hub
az eventhubs event-hub delete --name \
--namespace-name \
--resource-group
Managing Event Hubs using Azure SDKs
For more complex management tasks or integration into applications, use the Azure SDKs for your preferred programming language (e.g., Python, .NET, Java, Node.js).
Refer to the API Reference for detailed information on available management operations.
Best Practices
- Partitioning Strategy: Carefully choose the number of partitions based on your expected throughput and the number of consumers. More partitions allow for higher parallelism but can increase complexity.
- Naming Conventions: Use clear and consistent naming conventions for your Event Hubs.
- Monitoring: Regularly monitor Event Hubs metrics (e.g., incoming/outgoing messages, latency, errors) through the Azure portal or Azure Monitor to ensure optimal performance.
- Security: Use Shared Access Signatures (SAS) or Azure Active Directory (Azure AD) for authentication and authorization. Avoid hardcoding credentials.
