---------------------------------------
Summary: Introduce GroupingAnalyticsTransformer
Key: SPARK-54961
URL: https://issues.apache.org/jira/browse/SPARK-54961
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 4.1.0
Reporter: Mihailo Aleksic
In this PR I propose to introduce GroupingAnalyticsTransformer so we could
reuse grouping analytics related code in the single-pass implementation.
Besides the refactor we update nullabilities of Expand operator in place
instead waiting on UpdateAttributeNullability to trigger.
