Brian Hess commented on CASSANDRA-6477:
----------------------------------------
Can someone clarify whether, based on the current implementation, the
Materialized View (or some of the Materialized Views, if there are more than
one) can contain the mutation but the base table does not - or vice versa? Can
you clarify what happens in each of the failure scenarios? It will be very
important for us to know for sure when we discuss this with users/customers.

> 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.
