SINTERSTORE

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.

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.

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