    Description

      The current stats decimation levels are the following. This ticket tracks either confirming them for the initial release or changing them to a different default.

      decimation_definitions_default() ->
      		 
          [%% No decimation for the first 3 days
      		 
           {low, 3 * ?SECS_IN_DAY, skip},
      		 
           %% Keep 1 per minute for the next 4 days
      		 
           {medium, 4 * ?SECS_IN_DAY, 60},
      		 
           %% Keep 1 hour for the next 359 days
      		 
           {large, 359 * ?SECS_IN_DAY, 6 * 60 * 60}].
