> > > grouping - grouping by a lot of columns does not need ordering requirements > > How about implementing a specialization for Structs, the way we have for other types: [apache/datafusion@`main`/datafusion/physical-plan/src/aggregates/group_values/multi_group_by](https://github.com/apache/datafusion/tree/main/datafusion/physical-plan/src/aggregates/group_values/multi_group_by) > > That would likely be a lot faster than having to copy all the data once which a new row format would do @alamb in the case when we already need to convert to rows (in the fallback implementation) the ordering doesn't matter and we can use this new row format which will make it faster. -- This is an automated message from the Apache Git Service.
