Important Notes

• For details about technical specifications, see section “Technical Specifications” in Technical White Paper.
• Currently, openGauss supports a maximum of eight standby nodes. If one primary node and multiple standby nodes are used and the primary node is faulty, promote a standby node with more logs to primary, preventing other standby nodes from being rebuilt.
• You are advised to deploy one primary node and two standby nodes to ensure database reliability and availability.
