What is the relationship between Redis instances?
The master and slave instances are deployed in pairs. If a master instance is faulty, the remaining master instances in the cluster will select a slave instance to serve as the new master instance. The selection can be performed only when more than half of the master instances are normal. Each Redis cluster in a FusionInsight Farmer environment supports one-to-one mapping between active and slave instances.
