New in Cassandra 3.0: Materialized Views

Apache Cassandra introduces Materialized Views in version 3.0 as a feature that handles automated server-side denormalization, removing the need for client side handling of this process. This feature ensures eventual consistency between the base and view data, allowing for very fast lookups of data in each view using the normal Cassandra read path. Materialized views maintain a correspondence of one CQL row each in the base and the view, and can be used to track high scores for players of several games, among other applications. They are created by providing a simple select statement and the primary key to use for this view.
