Subject [jira] Commented: (HBASE-1249) Rearchitecting of server, client, API, key format, etc for 0.20
Date Thu, 19 Mar 2009 21:05:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1249?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12683614#action_12683614
] 

Erik Holstad commented on HBASE-1249:
-------------------------------------

I think that the idea is a the compareTo sits inside the Get interface and different Gets
implement their own methods.
But we didn't want to keep the compareto code on the client so that is why a serverside object
is created.
The idea of having a create stamp is just to be able to go to pass memCache and storefiles
faster incase of a timeRange query,
but that is an optimization.
