Subject [jira] [Commented] (CASSANDRA-6477) Materialized Views (was: Global Indexes)
Date Tue, 07 Jul 2015 15:25:09 GMT


Carl Yeksigian commented on CASSANDRA-6477:

[~aboudreault]: This was an unrelated issue - it was related to keeping track whether the
MV was built or not; I'm still looking at what is causing the inconsistency when a new node
has been added. I have only seen it occur once in my testing, but it would be good to catch.

[~iamaleksey]: I haven't done any cstar testing yet; have only done local stress. Would be
good to run that, though I don't think we can run it through the web interface as we'll need
to create the MV. /cc [~enigmacurry]

> 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.
