ZDIFF

Syntax
ZDIFF numkeys key [key ...] [WITHSCORES]
Available since:
6.2.0
Time complexity:
O(L + (N-K)log(N)) worst case where L is the total number of elements in all the sets, N is the size of the first set, and K is the size of the result set.

@read, @sortedset, @slow,

This command is similar to ZDIFFSTORE, but instead of storing the resulting sorted set, it is returned to the client.
