Data partitioningRedis clusters store data on multiple nodes, that is, different partitions are stored on different nodes, and each node can store multiple partitions. Each partition is also referred to as a "hash slot" in Redis, with a total of 16,384 partitions planned in the Redis cluster. For example: when there are 3 nodes in a cluster, Node A will contain 0-5460 partitions, Node B will contain 5461-10

First, design ideas:
When Master and Slave are operating normally, Master is responsible for service, Slave is responsible for standby;

When Master returns to normal, the data is synchronized from the slave, the master-slave copy function is turned off after the data is synchronized, and the master is restored, while sla
