Subject [jira] Commented: (CASSANDRA-749) Secondary indices for column families
Date Mon, 19 Apr 2010 07:35:51 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12858410#action_12858410

Stu Hood commented on CASSANDRA-749:
------------------------------------

Since local indexes aren't as useful for returning results in index order, and since they
are much better for low cardinality fields, perhaps they should be implemented as bitmap indexes?
