Subject [jira] Commented: (HBASE-1728) Column family scoping and cluster identification
Date Mon, 15 Feb 2010 21:40:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12833994#action_12833994
] 

Andrew Purtell commented on HBASE-1728:
---------------------------------------

@Ryan: Have you not seen the comments on several replication related issues where I have mentioned
using scope > 0 as global, with scope also used to sort a priority queue? That's what I
have in mind.

> Support column family scoping via a new HCD attribute. Provide initial set of scoping
constants and javadoc setting expectations for a simple default binary scoping policy: replicate,
or do not. Make the underlying type Integer so more complex edit routing policies are possible.
Also identify every HLogKey with the original cluster's ID.
