zinter.3valkey - Man Page

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

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.

• valkey-protocol(7) Array reply: the result of the intersection including, optionally, scores when the WITHSCORES option is used.

O(NK)+O(Mlog(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.
