   * `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.
+  * `OBJ_NAME_LENGTH` - if specified, then name of the object will be generated with the specified length of ASCII characters.
