-* `--soft_delete_window`_ (Optional, default= 604800 (i.e. 7 days)): Time window (in seconds) for considering soft-deleted objects..
-* `--agg_days`_ (Optional, default=30): The period over which to combine and aggregate results.
-* `--lookback_days`_ (Optional, default=360): Time window (in days) for considering the how old the bucket to be.
