A new module in Apache Spark that integrates relational processing with Spark’s functional programming API. Offers much tighter integration between relational and procedural in processing, through a declarative DataFrame API. Includes a highly extensible optimizer, Catalyst, that makes it easy to add data sources, optimization rules, and data types.
