I saw claims that Clusterix is very good for OLAP applications. Can you shed more light on it? Does it support materialized views for instance (to speed up calculating aggregation on higher levels) ?
We don't support materialized views at the moment, though I can't think of a reason why we couldn't support them if needed. A big strength for our OLAP performance is simply having CPU and memory resources that scale with storage and a query planner that is smart enough to take advantage of those resources.
