 * map is NOT backed by the original map, so changes to the original map are NOT reflected in the returned map, and vice-versa.
 * Please note that all the keys in the request should belong to the partition id to which this request is being sent, all keys
 * matching to a different partition id shall be ignored. The API implementation using this request may need to send multiple
