> See HBASE-11054 for discussion.  
> Currently the delete tracking is done by DeleteTracker and its subclasses.  column tracking
and its versions are handled inside the ColumnTrackers and its subclasses. 
> This JIRA aims at providing internal filters and attaching them to scans/gets, including
minor and major compaction scans so that all the logic of deletes and version counting goes
into it rather than having trackers.
