> Sometimes the original splits may have an ordering (eg. splits from a sorted file). Maintaining
the ordering of splits inside a group maintains the sort order.
> The node level grouping maintains ordering. When collecting leftover groups for rack
level grouping, the ordering is lost in current code.
