> Currently, statistics are not 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 minor 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.
