-------------------------------------
Summary: Update stats of table/partition after minor compaction
using noscan operation
Key: HIVE-26788
URL: https://issues.apache.org/jira/browse/HIVE-26788
Project: Hive
Issue Type: Improvement
Reporter: Sourabh Badhya
Assignee: Sourabh Badhya
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.
