The Clusters page in your PlanetScale dashboard allows you to monitor your cluster utilization and configure cluster settings for each branch in your database. You can:
  • Adjust the cluster size and instance type (Metal vs network-attached storage)
  • Configure the number of replicas
  • Monitor cluster utilization with real-time graphs
  • Configure storage settings including:
    • Disk size configuration
    • Autoscaling settings and thresholds
    • Storage limits
    • IOPS configuration
    • Bandwidth settings
  • Modify PostgreSQL parameters
  • Manage PostgreSQL extensions
  • View and track configuration changes
These settings may only be changed by a database administrator or organization administrator.

Adjusting cluster size

To adjust your cluster size:
1
From the PlanetScale organization dashboard, select the desired database
2
Navigate to the Clusters page from the menu on the left
3
In the Cluster size section, click on the cluster size dropdown
4
Select the new cluster size, (Metal or network-attached storage). If you select Metal, make sure you select the correct storage size.
5
Click Queue instance changes > Apply changes to apply the new cluster size
You cannot change the CPU architecture (AMD, Intel, ARM) of an existing cluster. To use a different architecture, you’ll need to create a new branch with the desired cluster type.
Cluster resizing may take several minutes to complete and you cannot make additional configuration changes until the resize is finished. Consider the case where you need to upgrade from an M-160 database cluster to an M-320, doubling the compute resources of each node. After applying the upgrade, three new M-320 nodes are created. These are caught up with the primary through a combination of a backup restore and data replication.
