PolarDB for PostgreSQL Distributed Edition charges separately for compute nodes (CNs) and data nodes (DNs). Two billing methods are available: pay-as-you-go and subscription.
Specification types
Choose a specification type based on your workload isolation requirements:
| Specification type | Description | Best for |
|---|---|---|
| General-purpose | Shares idle CPU and other compute resources with other clusters on the same physical server | Cost-sensitive workloads with flexible resource needs |
| Dedicated | Reserves all allocated CPU and compute resources exclusively for your cluster | Workloads requiring consistent performance and stronger resource isolation |
Read-only nodes
By default, one read-only CN or DN is added to each primary node when you create a cluster. The read-only node uses the same specifications as the primary node in the primary zone or primary data center and is billed separately.
Read-only nodes are discounted at 25% off the standard node price.
Pay-as-you-go
Pay-as-you-go charges by the hour with no upfront payment. Fees are deducted from your account balance hourly based on actual usage.
The following tables list hourly prices per single compute node.
By default, PolarDB for PostgreSQL Distributed Edition adds one read-only node to each compute node or data node to improve read performance.

Subscription
Subscription charges a fixed monthly fee paid upfront when you create the cluster.
The following tables list monthly prices per single compute node.
By default, PolarDB for PostgreSQL Distributed Edition adds one read-only node to each compute node or data node to improve read performance.
