> Currently, statistics are always updated for major compaction and never 
> updated for minor compaction since minor compaction performs little updates 
> on the statistics (such as number of files in table/partition & total size of 
> the table/partition). It is better to utilize NOSCAN operation  for both 
> these compaction since NOSCAN operations performs faster update of statistics 
> and updates the relevant fields such as number of files & total sizes of the 
> table/partitions if stats autogather is enabled. If autostats gather is 
> disabled then go for full update of statistics.
