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 5461-10922 partitions, and node C will contain 10923
