Modern web applications require fast reads of query results over user data. In practice, they use a complex, brittle, and tricky-to-manage caching layers to achieve this performance.

In this talk, I will discuss how we built a new database system, Noria, from the ground up around the paradigm of materialized view maintenance via incremental streaming dataflow. Noria combines eager and lazy dataflow processing to maintain partially-materialized views for an application’s queries with high performance and reasonable memory footprint, yielding 5-70x higher throughput than widely-used systems. Finally, I will preview our latest system, which uses a combination of lightweight per-user databases and materialized views to make privacy compliance (e.g., with the GDPR) painless for application developers.

This talk is part of the Vaccination Database Tech Talk Seminar Series.
