Dhruv Vats reassigned ARROW-15152:
----------------------------------
Assignee: Dhruv Vats
> Implement a `hash_list` aggregate function.
> -------------------------------------------
>
> Key: ARROW-15152
> URL: https://issues.apache.org/jira/browse/ARROW-15152
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++, Python
> Affects Versions: 6.0.1
> Reporter: A. Coady
> Assignee: Dhruv Vats
> Priority: Major
> Labels: good-second-issue, kernel
>
> For more advanced aggregations, it's helpful to be able to gather the grouped
> values into a list array. Pandas and Polars both have that feature. And
> `hash_distinct` already aggregates to lists, so all the building blocks are
> there.
