[jira] [Updated] (SPARK-56561) document where array_distinct and similar functions preserve order
[ https://issues.apache.org/jira/browse/SPARK-56561?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bill Schneider updated SPARK-56561:
-----------------------------------
Description:
It would be good for reference documentation of SQL functions to explicitly say when functions like `array_distinct` will (and won't) preserve order.
This would be useful to cite during code reviews, and may also help inform AI coding agents.
This might also apply to `array_intersect`.
