Presentation: "Timelines at Scale"
Time:
Friday 16:00 - 16:50
Location:
Grand Ballroom A
Abstract:
With hundreds of millions of users, Twitter operates one of the world's largest timeline delivery systems. At steady state, Twitter receives thousands of events a second whether it be tweets, social graph mutations, and direct messages -- these need to be delivered to disks, in-memory timelines, email, and mobile devices. Building, managing, and debugging this infrastructure is one of Twitter engineering's biggest challenges. In this session, we will dive into these paths to understand the architecture, as well as talk about some of the tools that Twitter uses to manage and understand these paths.
