Subject [jira] Commented: (CASSANDRA-749) Secondary indices for column families
Date Wed, 03 Feb 2010 20:59:28 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12829254#action_12829254

Jonathan Ellis commented on CASSANDRA-749:
------------------------------------------

I think having each node index its CFs locally is a lose for us, because as you say we have
to query the full cluster for any index lookup, since we are throwing away our usual partitioning
scheme.  

This means we add a ton of complexity (adding a completely different query path) in exchange
for not being able to scale these queries, since the work generated increases in lockstep
w/ machines added.
