---------------------------------------
Summary: ARRAY_EXCEPT should support set semantics
Key: FLINK-35423
URL: https://issues.apache.org/jira/browse/FLINK-35423
Project: Flink
Issue Type: Bug
Components: Table SQL / API
Reporter: Sergey Nuyanzin
After a number of discussions e.g. here [1]
It was decided to follow set semantics for {{ARRAY_EXCEPT}} and
{{ARRAY_INTERSECT}}.
It is marked as a blocker since {{ARRAY_EXCEPT}} was added in 1.20 only and has
not been released yet, so it the change should be done before release to avoid
inconsistencies.
