Subject [jira] [Commented] (CASSANDRA-6477) Materialized Views (was: Global Indexes)
Date Sun, 19 Jul 2015 00:50:09 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14632652#comment-14632652

T Jake Luciani commented on CASSANDRA-6477:
-------------------------------------------

If you lose data on the base or the view replica you will need to rebuild the corresponding
MV for just that node (much like secondary indexes)

This isn't hooked up in the patch. But the builder exists so I think it's a minor issue.

> 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.
