sinterstore.3valkey - Man Page

SINTERSTORE destination key [key...]

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.

O(N*M) worst case where N is the cardinality of the smallest set and M is the number of sets.
