Introducing improved Aiven Kafka topic management

Aiven Kafka users now have greater control over topic management with the introduction of new features such as creating, modifying, and deleting topics over the Kafka protocol. The updates improve interoperability between Aiven Kafka service instances and Kafka ecosystem applications and tooling. Automatic topic creation is also added as an option, which can be enabled using the Aiven Command Line Client. These modifications are available for existing Kafka services by triggering a maintenance update from within the Aiven console, and all new Aiven Kafka deployments will automatically include these updates.
