> 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.
