Expand a Dedicated Kafka Cluster in Confluent Cloud¶
This topic shows you how to expand an existing Dedicated Apache Kafka® cluster. Cluster expansion allows you to seamlessly scale your cluster to meet your streaming needs.
When you scale a Dedicated Kafka cluster, Confluent adds brokers and rebalances the cluster to ensure a balanced load across the brokers.
- An existing Dedicated Kafka cluster.
- Usage-based billing must be enabled.
Select your Confluent Cloud cluster.
Click the Cluster Settings tab and then Capacity.
View the current usage on your cluster and determine if you are hitting any usage limits. Click Expand capacity, select the expanded CKU capacity for your cluster, and then click Apply changes.
Cluster expansion is not reversible.
Confirm your changes and click Continue.
See Dedicated cluster provisioning and expansion time for guidance on how long expansion may take and variables that affect that timing.
