In three years, our servers scaled from processing zero to 500,000 queries per second. With 2000% growth in 2011, tens of millions of dollars of transactions taking place daily, a data pipeline bursting at the seams, and 24/7/365 uptime, AppNexus engineers faced a task likened to changing the engine of a 747 in midflight.
This talk will explore how we horizontally scaled our pipeline and data reporting by adapting a variety of technologies, including Hadoop, Vertica, NoSQL, MySQL, and more. In this session you will gain from our experience and hear our lessons-learned in terms of hardware application, monitoring, rollback, failover nodes, controlling memory allocation, and day-to-day fire drills. We will cover the data flow between different systems, integration details, job scheduling, common pitfalls, and the finely tuned solutions that we have developed.
