Instance Specifications
- x86 instances support general-purpose and dedicated editions.
- Kunpeng instances support only dedicated edition.
For information about Transactions Per Second (TPS) and Queries Per Second (QPS), see Performance White Paper.
Instance Specifications |
Description |
Scenario |
Constraint |
---|---|---|---|
Dedicated (recommended) |
An instance contains one primary node and up to 15 read replicas. Its CPU and memory resources are dedicated for use and performance is stable without being affected by other instances on the same physical machine. |
It is suitable for scenarios that require high performance stability. |
It is available only for regions listed in Table 2. |
General-purpose |
An instance contains one primary node and up to 15 read replicas. CPU and memory resources are shared with other general-purpose DB instances on the same physical machine. CPU usage is maximized through resource overcommitment. It is cost-effective. |
It is suitable for scenarios where performance stability is not critical. |
It is available only for regions listed in Table 2. |
