---------------------------------------------
Actually to be an assignee that means you have to be a contributor, so if we
add someone who hasn't contributed before just to assign, then they never post
a patch, we have go undo the addition which is painful. Much better to just
leave a comment, post a patch, then we'll assign on commit.
> Avoid constant boxing in ColumnStats.{Min/Max}Tracker

> 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.
