SUNIONSTORE destination key [key ...]

自1.0.0起可用。

时间复杂度: O(N)其中N是所有给定集合中元素的总数。

该命令与SUNION相同,但不是返回结果集,而是存储在中destination

如果destination已经存在,它将被覆盖。

返回值

整数回复:结果集中元素的数量。

例子

redis>  SADD key1 "a" (integer) 1 

redis>  SADD key1 "b" (integer) 1 

redis>  SADD key1 "c" (integer) 1 

redis>  SADD key2 "c" (integer) 1 

redis>  SADD key2 "d" (integer) 1 

redis>  SADD key2 "e" (integer) 1 

redis>  SUNIONSTORE key key1 key2 (integer) 5 

redis>  SMEMBERS key 1) "a" 2) "c" 3) "e" 4) "b" 5) "d"
