SINTERSTORE

Syntax

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.

ACL categories: @write, @set, @slow

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

If destination already exists, it is overwritten.

Return

Integer reply: the number of elements in the resulting set.
