Aleksey Yeschenko commented on CASSANDRA-6477:
----------------------------------------------
I've got an issue with how MVs are represented in schema, but, more
user-visibly, a minor issue on the DDL side. Or, rather, two issues:
1. We have {{CREATE MATERIALIZED VIEW}}, {{DROP MATERIALIZED VIEW}}, but we
reuse {{ALTER TABLE}} to modify it. We should have {{ALTER MATERIALIZED VIEW}}
instead.
2. It's currently impossible to override things like compaction and compression
parameters in {{CREATE MATERIALIZED VIEW}}. Users shouldn't need to issue a
follow up {{ALTER MATERIALIZED VIEW}} to set the parameters. {{CREATE
MATERIALIZED VIEW}} should support {{WITH}}.

> 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.
