Details

In this technical talk, Gilt Principal Software Engineer Adam Kaplan will describe the engineering behind Gilt's push notification system, which can send three million messages in less than 60 seconds. Adam will give a brief history of push notifications at Gilt, then focus on the development of his team's current system: a distributed architecture built with Scala, Akka, ZooKeeper, and other technologies. He'll explain how Akka's clustering capabilities not only make mass messaging possible, but also promote overall system integrity, scalability, and better performance (and, on the business side of things, higher revenues!). He'll place push notifications in the context of Gilt's general engineering culture, which emphasizes a micro-services architecture, fault tolerance, and (the good kind of) redundancy. Finally, he'll give a forward-looking view of where push at Gilt is going -- and how the work his team performs ensures that all of those millions of messages stay on the right side of that line between "push notifications" and "spam."
