PolarDB-X 1.0 instances and PolarDB-X 1.0 instances are classified into different instance specifications based on the CPU processing capability, memory capacity, and disk space. Instances of multiple different specifications are provided for selection. A higher specification indicates the higher processing capability on the instance. This topic describes how to select instance specifications.
Select a type and a specification of your PolarDB-X 1.0
PolarDB-X 1.0 instances are all the dedicated instances. Each instance provides at least two nodes to ensure high availability. A PolarDB-X 1.0 provides compute-intensive services. Its processing capability is relevant to the CPU and measured by the metric: queries per second (QPS). When you select an instance, you must refer to the maximum QPS that is supported by different specifications, and the estimated maximum QPS of your business.
