Subject [jira] Created: (HBASE-610) Autoincrementing cell version
Date Wed, 30 Apr 2008 21:36:55 GMT
Autoincrementing cell version
-----------------------------

                 Key: HBASE-610
                 URL: https://issues.apache.org/jira/browse/HBASE-610
             Project: Hadoop HBase
          Issue Type: Improvement
            Reporter: stack
             Fix For: 0.2.0


HBASE-609 has an example of clock skew making it so master scanner missed edits placed there
by a regionserver whose clock was in advance of the masters.  There may be other cases lurking
where this kind of issue -- two servers are updating a particular row with off-clocks -- may
bite us.  Could a regionserver that has a clock a long ways behind the running master's clock
enter a split record that went in behind the current inforegion cell's version?  If so, the
master wouldn't see the split.

One fix would be a new feature where cells had a version that autoincremented.
