PolarDB-X 1.0 instances are classified by CPU processing capability, memory capacity, and disk space. All instances are dedicated instances with at least two nodes for high availability. Processing capability is measured in queries per second (QPS). Use this topic to choose the right edition and specification for your workload.
Choose an edition
Use the following table to identify the edition that matches your workload, then review the full specification list for that edition.
| Edition | Target workload | Parallel queries |
|---|---|---|
| Starter Edition | Early-stage development and testing | Not available |
| Standard Edition | Online workloads requiring high concurrency, complex queries, and lightweight analysis | Enabled by default |
| Enterprise Edition | Enterprise workloads requiring ultra-high concurrency, large-scale complex queries, and accelerated reporting | Enabled by default |
The Starter Edition does not support query acceleration for complex queries.
Compute instance specifications
When selecting a specification, compare the maximum QPS supported by each specification against the estimated peak QPS of your workload.

Select a storage specification
To choose the right storage configuration:
-
Estimate the maximum disk space required based on your expected business growth over the next one to two years.
-
Estimate the maximum input/output operations per second (IOPS) required by a single PolarDB-X 1.0 instance.
To support fast scaling when a storage bottleneck is encountered, purchase multiple PolarDB-X 1.0 instances with small or medium specifications rather than a single large instance.
