Executes a particular query on specified region using a set of keys that represents buckets . The set of buckets is determined by keys of entries that are stored in such buckets : - real and fake keys can be used ( such key should have the same routing object as bucket s keys have ) ; - it will be enough to specify one key for each bucket . Work of this method is based on execution of function .
