When we look at the default Azure Event Hub we have Event Hub Namespaces and we have the possibility to create Event Hubs within those Namespaces. In Apache Kafka you have Topics.
Is Topic the same as an Event Hub within an Event Hub Namespace?
Here is an overview of the Kafka and Event Hub conceptual mapping:
Kafka Concept Event Hubs Concept
| Kafka Concept | Event Hubs Concept |
|---|---|
| Cluster | Namespace |
| Topic | Event Hub |
| Partition | Partition |
| Consumer Group | Consumer Group |
| Offset | Offset |
