How Do I Select Specifications and Nodes When Creating a GeminiDB Redis Instance?

GeminiDB Redis provides multiple instance specifications. The performance depends on the instance specifications and the number of nodes. This section summarizes some practical experience to help you determine the instance specifications and node quantity.

1. Higher specifications can provide better performance. For details about the supported instance specifications, see Instance Specifications.
2. If the instance specifications are the same, more nodes provide better performance.
3. Select specifications that can meet your service requirements based on the test data and reserve some resources for reliability redundancy and future service growth.
4. Generally, a single-core CPU has good performance when the data size is 16 GB. For example, if the service data volume is 128 GB and is not expected to increase any further, you can purchase two instances each with 4 vCPUs and 16 GB memory.
