Scaling

​

Overview

​

Node limits

​

Add a node

1. Navigate to your cluster’s detail page in the dashboard.
2. Open the Management tab.
3. Click Add Node.
4. Review the cost impact (adds one node at your current plan’s per-node price).
5. Confirm the operation.

​

What happens

• A new server is provisioned in the same region as your cluster.
• PostgreSQL is installed and configured to match your cluster settings.
• The new node joins the cluster as a replica and begins streaming replication from the primary.
• Prometheus exporters are configured for monitoring.
• The operation typically takes 3-5 minutes.
• You can track progress in real time via the dashboard.

​

Remove a node

1. Navigate to your cluster’s detail page.
2. Open the Management tab.
3. Click Remove Node.
4. Select the node to remove from the list.
5. Type the node name to confirm.
6. Confirm the operation.

​

What happens

• The selected node is removed from the cluster.
• If the removed node was a replica, no failover occurs.
• If the removed node was the primary, Patroni automatically promotes a replica to primary before removal.
• The server is decommissioned.
• Your subscription is updated to reflect the new node count.

​

Scaling constraints

• One operation at a time: You cannot add or remove nodes while another job (backup, restore, scaling, or configuration) is in progress.
• Cluster must be active: Scaling is only available for clusters in an active state.
• No vertical scaling yet: To change server type (e.g., Starter to Growth), create a new cluster and migrate your data. Vertical scaling is on our roadmap.

​

Billing impact

• Adding a node increases your monthly cost by one unit of your plan price (e.g., +$39/mo for Growth).
• Removing a node decreases your monthly cost accordingly.
• Billing is prorated within the current billing cycle.
