In an expanded partnership between the world's biggest social network and travel sites, TripAdvisor became one out of eight companies to join Facebook's "instant personalization" service - a feature that highlights Facebook friends' interests, as users visit participating sites. Instant personalization is an opt-out instead of an opt-in feature for users, resulting in many users being personalized while visiting TripAdvisor.com, with more than 100M users.

This talk is about how we handle the avalanche of "Instant Personalization" data, specifically how we personalize the user's experience with limited impact on the web site and acceptable latency for the users without adding a single piece of hardware. Moreover, annotating user-contributed content as from "a friend of a friend" offers many more opportunities to de-anonymize content than using only the first-degree friend network.  We'll talk about how we accomplished this using a combination of on-demand friend data and offline processing with Hadoop/Hive.
