Create a DSP connection to Microsoft Azure Event Hubs

To get data from Microsoft Azure Event Hubs into a data pipeline in the , or send data from a pipeline to an event hub, you must first create a connection. You can then use the connection in the Microsoft Azure Event Hubs source function or sink function.

Send to Microsoft Azure Event Hubs is a beta function and not ready for production.

Prerequisites

Before you can create an Azure Event Hubs connection, you must have the following:

• The shared access signature (SAS) key and name for accessing your Azure Event Hubs resources. If you don't have these credentials, ask your Azure Event Hubs administrator for assistance.
• Outbound ports 5671 and 5672 open in the firewalls of all the nodes in the DSP cluster. If these outbound ports are not open, DSP cannot communicate with Azure Event Hubs. Ask your DSP administrator to confirm the port configurations and open the ports if needed.

Steps

1. From the Data Stream Processor home page, click Data Management and then select the Connections tab.
2. Click Create New Connection.
3. Select Connector for Microsoft Azure Event Hubs and then click Next.
4. Complete the following fields:

   Field	Description
   Name	A unique name for your Azure Event Hubs connection.
   Description (Optional)	A description of your your Azure Event Hubs connection.
   Namespace name	The name of the Azure Event Hubs namespace used to read and write events
   SAS name	The name of the Shared Access Signature (SAS) key used to authenticate to Azure Event Hubs.
   SAS key	The SAS key used to authenticate to Azure Event Hubs. Your shared access key must have listening privileges for the namespace.

   Any credentials that you upload are transmitted securely by HTTPS, encrypted, and securely stored in a secrets manager.

5. Click Save.

   If you're editing a connection that's being used by an active pipeline, you must reactivate that pipeline after making your changes. When you reactivate a pipeline, you must select where you want to resume data ingestion. See Using activation checkpoints to activate your pipeline in the Use the Data Stream Processor manual for more information.

You can now use your connection in a Microsoft Azure Event Hubs source function at the start of your data pipeline to get data from Azure Event Hubs, or in a Send to Microsoft Azure Event Hubs sink function at the end of your pipeline to send data to Azure Event Hubs.
