Redis Cluster

不能在 Redis Cluster 上执行 SUNION 等命令

Redis Cluster implements all the single key commands available in the non-distributed version of Redis. Commands performing complex multi-key operations like Set type unions or intersections are implemented as well as long as the keys all belong to the same node. —— Implemented subset

所以不能再 Redis Cluster 上执行多个 key 操作的命令,SINTER、SUNION、SDIFF、ZUNIONSTORE、ZINTERSTORE 都是不能使用的。(即使没报错,结果也是不正确的)
