SINTERSTORE destination key [key …]

    Time complexity: O(N*M) worst case where N is the cardinality of the smallest set and M is the number of sets.

    This command is equal to SINTER, but instead of returning the resulting set, it is stored in .

    If destination already exists, it is overwritten.

    *Examples

    redis> SADD key1 "a"

    redis> SADD key1 "b" 

    1. (integer) 1

    redis> SADD key1 "c"

      redis> SADD key2 "d"

      redis> SADD key2 "e" 

      1. (integer) 1

      redis> SINTERSTORE key key1 key2
