Noria: dynamic, partially-stateful data-flow for high-performance web apps

This is something that I've been hoping to see for a while. The traditional model of web apps, with a database backend but doing manual de-normalization, adding manual caching and cache invalidation, or using manually created and expensive materialized views, seems complex, fiddly, and fragile.

The database engine should be able to build the necessary cache of intermediate state from the queries used by the application; and this shows that that is in fact possible.
