Apache Spark reassigned SPARK-41635:
------------------------------------
Assignee: Reynold Xin (was: Apache Spark)
> GROUP BY ALL
> ------------
>
> Key: SPARK-41635
> URL: https://issues.apache.org/jira/browse/SPARK-41635
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Reynold Xin
> Assignee: Reynold Xin
> Priority: Major
>
> This patch implements GROUP BY ALL, similar to the one initially implemented
> in DuckDB. When specified, the analyzer automatically infers the grouping
> columns based on the expressions specified in the select clause: all
> expressions that don't include any aggregate expressions are pulled
> implicitly into the grouping columns. This avoids users having to specify
> individually the list of grouping columns in most cases.
> Examples:
> {{select key, count(*), sum(score) from table group by all}}
> {{-- rewritten to}}
> {{select key, count(*), sum(score) from table group by key}}
