SINTERSTORE

Syntax
SINTERSTORE destination key [key ...]
Available since:
1.0.0
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.
