Subject [jira] [Commented] (CASSANDRA-6477) Materialized Views (was: Global Indexes)
Date Thu, 21 May 2015 01:01:01 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14553457#comment-14553457

Jonathan Ellis commented on CASSANDRA-6477:
-------------------------------------------

bq. When overloaded with inserts to a single partition key in the base, tombstones aren't
always properly generated for the view

Because of a race on index maintenance, or because we're load shedding?

> 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.
