Valkey is a high-performance, open-source database that stores key-value data in memory, and is designed for caching, message queues, and primary database use. Fully compatible with Redis, Valkey serves as a drop-in replacement.
You can resize existing Valkey database clusters at any time to add more CPUs, RAM, and storage. To avoid data loss, you cannot decrease the size of database clusters.
Resize a Database Cluster Using the CLI
To resize a database cluster using doctl
, you need to provide a value for the --size
flag, which specifies the cluster’s new configuration (number of CPUs, amount of RAM, and hard disk space). Use the doctl databases options slugs
command to get a list of available values.
Resize a Database Cluster Using the API
To resize a database cluster using the API, you need to provide a value for the size
field, which specifies the cluster’s configuration (number of CPUs, amount of RAM, and hard disk space). Use the /v2/databases/options
endpoint to get a list of available values.
Resize a Database Cluster Using the Control Panel
To resize a Valkey database cluster, click the name of the cluster in the control panel to go to its Overview page, then click the Settings tab.
In the Cluster configuration section, click the Edit button. Select a Droplet plan and optionally add standbynodes.

Once you have selected your new configuration, click Save to provision the new configuration. The provisioning takes several minutes but the total time depends on the size of the cluster.
Your cluster’s state changes from Active to Resizing until the process is done. You can expect no downtime and do not need to take action.
