   * `DELETE_AGE` - age of object in seconds before which it can not be deleted. This parameter can be used to control how many objects we have in the system under load.
   * `SLEEP_DELETE` - time interval (in seconds) between deleting VU iterations.
   * `OBJ_NAME` - if specified, this name will be used for all write operations instead of random generation.
+  * `DIR_HEIGHT`, `DIR_WIDTH` - if both specified, object name will consist of `DIR_HEIGHT` directories, each of which can have `DIR_WIDTH` subdirectories, for example for `DIR_HEIGHT = 3, DIR_WIDTH = 100`, object names will be `/dir{1...100}/dir{1...100}/dir{1...100}/{uuid || OBJ_NAME}`
