- Usage:
-
ZINTER numkeys key [ key ... ] [ WEIGHTS weight ] [ [ WEIGHTS weight ] ... ] [ AGGREGATE SUM | MIN | MAX ] [ WITHSCORES ]
- 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.
- Since:
- 6.2.0
- ACL Categories:
- @sortedset, @read, @slow
- Array reply: the result of the intersection including, optionally, scores when the WITHSCORES option is used.
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.
