Subject [jira] Commented: (CASSANDRA-1415) Allow creating indexes on existing data
Date Thu, 26 Aug 2010 16:35:54 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1415?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12902921#action_12902921
] 

Gary Dusbabek commented on CASSANDRA-1415:
------------------------------------------

01: it looks like the old version built the index by reading straight from the data file.
 The new way expects the CFS to be populated with sstables, which isn't always going to be
the case (if you're recovering from a descriptor that points to a db that the CFS isn't going
to load automatically).
