What Are the Differences Between Kafka Queues and Kafka Premium Instances?

  • Creation:

    When you apply for a Kafka premium instance, an exclusive instance is created and runs on an ECS in a VPC. You can create multiple topics in a Kafka premium instance and customize the number of partitions. A Kafka queue is equivalent to a Kafka topic, and three partitions are configured by default.

  • Resource allocation:

    Kafka premium instances are a new type of resource provided by DMS. After creating a Kafka premium instance, you can exclusively use physically isolated resources in the instance.

  • Client connection:

    Kafka queues require tenant identity authentication for logical isolation. Therefore, token authentication is added to the DMS SDK based on the open-source Kafka SDK. By contrast, Kafka premium instances support client-based access in a VPC. With the secure access control provided by the VPC, you can access Kafka premium instances by using the open-source SDK.
