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.
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.
