Kafka settings

Kafka settings affect the performance of the database cluster.When you create a Kafka database cluster, the values for all settings are set automatically.The values are chosen to ensure high cluster performance and vary depending on the cluster configuration.

If the automatic values are not suitable for your tasks, set your own values when creating the cluster or change the settings in the created cluster.
