 Setting resource limits will allow your cluster to scale to meet your application's needs and maintain a high level of performance. You must [set resource limits]({% link cockroachcloud/basic-cluster-management.md %}#edit-cluster-capacity) if you've already created one free CockroachDB {{ site.data.products.basic }} cluster. To set your limits, you can either set storage and RU limits individually, or enter a dollar amount that will be split automatically between both resources. You can also choose an unlimited amount of resources to prevent your cluster from ever being throttled or disabled.
