ZINTER

ZINTER numkeys key [key ...] [WEIGHTS weight [weight ...]]
  [AGGREGATE <SUM | MIN | MAX>] [WITHSCORES]

Available since:

6.2.0

Time complexity:

O(N*K)+O(M*log(M)) worst case with N being the smallest input sorted set, K being the number of input sorted sets and M being the number of elements in the resulting sorted set.

ACL categories:

@read, @sortedset, @slow,

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

For a description of the WEIGHTS and AGGREGATE options, see ZUNIONSTORE.
