SINTERSTORE

Stores the intersect of multiple sets in a key.

Usage: SINTERSTORE destination key ...
Complexity: O(N*M) worst case where N is the cardinality of the smallest set and M is the number of sets.
Since: 1.0.0
ACL Categories: @set, @slow, @write
Command flags: WRITE, DENYOOM

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.
