Subject [jira] Commented: (HBASE-1249) Rearchitecting of server, client, API, key format, etc for 0.20
Date Wed, 01 Apr 2009 17:34:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1249?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12694631#action_12694631
] 

Jonathan Gray commented on HBASE-1249:
--------------------------------------

Right.  My idea was just to use NOW as the storefile seqid/flushid (if future timestamps are
not allowed, we maintain a property of no versions in a storefile being newer than the seqid/flush
stamp).  Nothing fancy like getting the newest version of the flush or anything, don't think
that's necessary.
