Scale up the Kafka cluster

A Kafka cluster can be scaled — for example, increase vCPU and RAM to improve cluster performance.

You can change a fixed node configuration to an arbitrary configuration or an arbitrary configuration to a fixed configuration, but only with more disk space. You can reduce or increase the number of vCPUs and RAM. Look at the list of Kafka node configurations.

While the changes are being applied, the master node will be stopped and the cluster will be temporarily unavailable for reads and writes.

The configuration change time depends on the amount of data in the cluster.

  1. In Control Panel, go to Cloud Platform → Databases.
  2. Open the cluster page → Settings tab.
  3. Click Scale Cluster.
  4. Select another fixed or arbitrary configuration. You can only select a configuration with more disk space. The amount of vCPU and RAM can be decreased or increased.
  5. Click Save.
