Subject [jira] Commented: (HBASE-1249) Rearchitecting of server, client, API, key format, etc for 0.20
Date Wed, 29 Apr 2009 22:16:30 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1249?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12704375#action_12704375

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

@Stack
I don't really know exactly where the big improvement comes from compared to the old code,
but I don't think that it is that weird that we see a big improvement even though the x factor
might not be totally true. And I'm not going to say that I haven't missed anything in the
new code, cause that would just be really silly, but I think atleast we have some good numbers
to work with. But since I don't have a working patch just yet, these number should be more
as guidelines than actual numbers to compare.
