Sourabh Badhya updated HIVE-26788: ---------------------------------- Status: Patch Available (was: Open) > Update stats of table/partition using noscan operation when stats autogather > is enabled > --------------------------------------------------------------------------------------- > > Key: HIVE-26788 > URL: https://issues.apache.org/jira/browse/HIVE-26788 > Project: Hive > Issue Type: Improvement > Reporter: Sourabh Badhya > Assignee: Sourabh Badhya > Priority: Major > Labels: pull-request-available > Time Spent: 5h 20m > Remaining Estimate: 0h > > 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
