> For KeyGroupedPartitioned scans, the InternalRowComparableWrapper does a
> cache lookup of the current data types to create a schema and ordering for
> the given types. When there are a large number of partitions, this cache
> lookup (which occurs in many places once per partition) can become a
> bottleneck on physical planning.
