Subject [jira] [Commented] (CASSANDRA-6477) Materialized Views (was: Global Indexes)
Date Fri, 24 Jul 2015 16:27:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14640702#comment-14640702

Benedict commented on CASSANDRA-6477:
-------------------------------------

Well, I guess we know upfront if the table has an MV, so we only need to do it then. We need
to comment the faeces out of this, though, so nobody screws this up later. It's a very specific
relationship we'll probably forget.

> Local indexes are suitable for low-cardinality data, where spreading the index across
the cluster is a Good Thing.  However, for high-cardinality data, local indexes require querying
most nodes in the cluster even if only a handful of rows is returned.
