Resizing a Cluster¶
When creating a cluster, you can determine the cluster capacity with several parameters:
The machine type based on storage/#CPU/memory size.
The number of machines.
ScyllaDB Cloud will deploy the cluster based on your specification. Later on, you can resize your cluster based on the needs of your application - you can monitor your workload’s utilization with ScyllaDB Monitoring tools and statistics.
Resizing a Regular Cluster¶
To resize a cluster:
Ensure you have the ADMIN role.
Choose Action> Resize Cluster in your cluster’s view to resize your cluster. You can:
Increase or decrease the number of nodes. The number of nodes you can add equals or is a multiple of the Replication Factor set for your cluster (the default is 3).
Modify the instance type to smaller or larger machines (cluster resize is not supported for t3.micro and e2.micro instances).
If you are increasing the number of nodes, the new node(s) will be added to the datacenter you are already using. To add nodes in a new datacenter, see Adding a Datacenter.
Note
Resizing might take a significant amount of time, between a few hours and a full day, depending on your cluster.
Resizing a Vector Search Cluster¶
If Vector Search is enabled on your cluster, you can resize regular nodes as described above. To resize the Vector Search nodes, use the Resize Vector Search option from the three-dot menu in the datacenter overview section or the ScyllaDB Cloud API.
See Resizing a Vector Search Cluster for detailed instructions.
