Jon Haddad commented on CASSANDRA-6477:
---------------------------------------

Not a fan of materialized query tables personally.  

To put it in context, we frequently refer to the various tables that people need to create
to query their data as materialized views, and people seem to understand immediately.

> 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.
