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)
