Lars George commented on HBASE-7:
---------------------------------

>From http://devblog.streamy.com/2009/08/09/hbase-hackathon-2-day-one/

* Sequence IDs
-  Change to stamps?
-  Must be unique
-  Fix for merges
* Start/end keys match
-  Figures out / runs merges
* Repair references
* Two modes
-  Quick mode scans META
-  Full mode reads HFiles and verifies fully
