Scala Days 2012: Nathan Hamblen on Remixing the Abstraction Compromise
Remixing the Abstraction Compromise
While essential to managing complexity, abstractions in software programming usually come with a cost in runtime performance. Deeper abstractions allow programmers to remix this compromise: with low-level access preserved in high-level interfaces, we can create the best mix of performance and convenience for each application.

At Meetup our application architecture for conventional web requests is the Java servlet container. When we wanted to provide an efficient streaming service with interfaces in WebSockets and long-polling HTTP, we built it in Scala atop Unfiltered and Netty. This service performed as well as expected, but the greatest benefits came when we realized that the same model suits certain operations handled in our traditional stack. By employing deeper abstractions in Scala we replaced the blunt, high-level abstraction of Java Servlets with carefully tuned Netty Handlers, dramatically improving the performance of an important service and clearing the path to its long-term scalability.
