Subject [jira] Commented: (HADOOP-1391) HBase administration
Date Fri, 18 May 2007 22:27:16 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1391?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12497061

Jim Kellerman commented on HADOOP-1391:
---------------------------------------

Bigtable applies attributes on a per column basis. For example, the number of versions kept
for a column family, access control, compression are all per column family attributes. Currently
max versions is a per table attribute in HBase. Since we are going to be modifying table and
column descriptions for this set of enhancements, we should take this opportunity to make
max versions a per column attribute as well.
