Azure EventHubs

This page describes connection Lenses to Azure EventHubs.

Azure EventHubs only support delete or compact as a topic cleanup policy.

Only one Kafka connection is allowed.

The name must be kafka.

See JSON schema for support.

Environment variables are supported; escape the dollar sign

Create a Data Integration API key

• Add a shared access policy

  • Navigate to your Event Hub resource and select Shared access policies in the Settings section.

  • Select + Add shared access policy, give a name, and check all boxes for the permissions (Manage, Send, Listen)

• Once the policy is created, obtain the Primary Connection String, by clicking the policy and copying the connection string. The connection string will be used as a JAAS password to connect to Kafka.

• The bootstrap broker [YOUR_EVENT_HUBS_NAMESPACE].servicebus.windows.net:9093
