| Stable and reliable | High availability of master/slave servers, second-level failover of nodes, regular automatic backup, and automatic management of backup files | The node failover is complicated and affects normal service. It is required to manage the database backup. |
| Superior performance | Due to the superior performance, you can create multiple read-only replicas. Also, it has the read-write separation feature. | It has the self-developed read-write separation feature and allow you to achieve self-maintained data synchronization of read-only replicas. |
