ZINTERSTORE destination numkeys key [key ...] [WEIGHTS weight [weight ...]] [AGGREGATE SUM|MIN|MAX]

自2.0.0起可用。

时间复杂度: O(N * K)+ O(M * log(M))最坏的情况,N 是最小的输入排序集合,K 是输入排序集合的数量,M 是结果排序集合中的元素数量。

计算numkeys由指定键给出的已排序集合的交集,并将结果存储在中destinationnumkeys在传递输入键和其他(可选)参数之前,必须提供输入键()的数量。

默认情况下,元素的结果得分是其存在的有序集合中的得分总和。因为交集需要一个元素成为每个给定的有序集合的成员,所以这导致结果集合中的每个元素的得分等于输入的有序集合的数量。

有关WEIGHTSAGGREGATE选项的说明,请参阅 ZUNIONSTORE 。

如果destination已经存在,它将被覆盖。

返回值

整数回复:在destination得到的排序集中的元素数。

例子

redis>  ZADD zset1 1 "one" (integer) 1 

redis>  ZADD zset1 2 "two" (integer) 1 

redis>  ZADD zset2 1 "one" (integer) 1 

redis>  ZADD zset2 2 "two" (integer) 1 

redis>  ZADD zset2 3 "three" (integer) 1 

redis>  ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 (integer) 2 

redis>  ZRANGE out 0 -1 WITHSCORES 1) "one" 2) "5" 3) "two" 4) "10"
