Create a diskless topic Limited availability

You can create diskless topics after Aiven provisions your Aiven for Apache Kafka® service configured with Diskless Topics.

When you create a Kafka topic, you must choose a topic type: diskless or classic. You cannot change the type after the topic is created. Diskless topics have some feature limitations. For details, see Diskless Topics limitations.

note

Diskless Topics is in limited availability. Aiven provisions the service and manages the setup in your cloud account. Self-service support is coming soon. To request access, contact Aiven.

Steps to create a diskless topic

Console

1. Log in to the Aiven Console and select your Aiven for Apache Kafka® service.
2. Click Topics in the sidebar.
3. Click Create topic and enter a name for the topic.
4. Optional: Click Advanced settings to configure additional topic parameters.
5. Set properties such as the replication factor, number of partitions, and other settings. You can update these later.
6. Click Create topic.
