AdRoll uses large-scale machine learning to bid intelligently in internet advertising auctions. In this post, we explore some of the engineering behind the data pipelines that feed our learning algorithms, in particular our real-time system that constructs features from event streams.| NextRoll
In rolling out our real time bidding infrastructure, we were faced with the task of syncing data for every user we could possibly target across four regions. We have on the order of hundreds of millions of users, and tens of thousands of writes per second.
