> We use the {{ColumnStats.MinTracker}} and {{ColumnStats.MaxTracker}} to track
> timestamps and deletion times in sstable. Those classes are generics but we
> really ever use them for longs and integers. The consequence is that every
> call to their {{update}} method (called for every cell during sstable write)
> box it's argument (since we don't store the cell timestamps and deletion time
> boxed). That feels like a waste that is easy to fix: we could just make those
> work on longs only for instance and convert back to int at the end when
> that's what we need.
