Single Node
Huawei Cloud has discontinued the sale of DDS single node instances since July 15, 2023.
Instances of the same type have different memory specifications. You can select instances of different specifications based on application scenarios.
This section describes single node instance specifications. The instance specifications depend on the selected CPU model.
The default maximum number of connections has been adjusted. Query the number of connections based on the instance creation time. For details about the number of connections for instances created before July 2021, see Historical Instance Specifications.
Instance Specifications
DDS single node instances have two specification types: general-purpose and enhanced II. For details, see Table 1.
Specification Type |
Description |
Applicable Scenario |
---|---|---|
General-purpose |
CPU resources are shared with other general-purpose DB instances on the same physical machine. CPU usage is maximized through resource overcommitment. This instance class is a cost-effective option and suitable for scenarios where performance stability is not critical. |
Suitable for scenarios that have high requirements on cost-effectiveness. |
Enhanced II |
With a leading network acceleration engine and Data Plane Development Kit (DPDK) fast packet processing mechanism, this instance class provides higher network performance and computing power. |
Suitable for websites and web applications that require high database computing and network performance. |
