The compute nodes of PolarDB for MySQL Cluster Edition, Multi-master Cluster (Database/Table) Edition, and X-Engine Edition are classified into two types: General-purpose and Dedicated. This topic describes the differences between the two types of compute nodes.
Compute node types
| Compute node type | Feature | Scenario |
|---|---|---|
| Dedicated |
| Scenarios in which databases are the key component of business systems that require high reliability, such as finance, e-commerce, public service, and medium- or large-scale Internet services. |
| General-purpose |
| Scenarios in which cost-effectiveness is prioritized. |
