Does Primary/Standby Switchover Have Impact on Services?
Primary/standby switchover may cause service interruption for some seconds or minutes (determined by the replication delay). If the primary/standby synchronization delay is too long, a small amount of data may get lost. To prevent traffic congestion, you are advised to perform switchover during off-peak hours.
