Subject [jira] [Commented] (HBASE-5723) Simple Design of Secondary Index
Date Thu, 05 Apr 2012 17:58:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5723?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13247438#comment-13247438

Todd Lipcon commented on HBASE-5723:

The design doc doesn't make any reference to consistency. How do you ensure consistency of
the index? To do proper indexes you really need cross-table transactions, or at least a mechanism
for eventual consistency if that's all you plan on providing.
