I have a scenario where the messages in the service bus topic has to be subscribed by a Event Hub. Can any one tell how to integrate Azure Service Bus and Event Hub?
You can leverage Azure Logic app fro this.
You can use Service Bus trigger i n Logic app . Follow the doc https://learn.microsoft.com/en-us/azure/connectors/connectors-create-api-servicebus
