   Yes, but singleton version ([v,v]) rowsets which must be wrote by sink, and 
they haven't do cumulative compaction (compacted rowsets' version [u, v], v 
must larger than u, not equal), they should be after compaction point, no mater 
they are NONOVERLAPPING or OVERLAPPING. Becasue newly generated singleton 
verison rowset with single segment is set as NONOVERLAPPING:

   So we should not skip these kind of rowset when calculate cumulative point, 
right?
