Processing Billions of Events in Real-Time with Heron - Karthik Ramasamy, Twitter

Twitter generates tens of billions of events per hour when users interact with it. Analyzing these events to surface relevant content and to derive insights in real time is a challenge. To address this, we developed Heron, a new real time distributed streaming engine. In this talk, we first describe the design goals of Heron and show how the Heron architecture achieves task isolation and resource reservation to ease debugging, troubleshooting, and seamless use of shared cluster infrastructure with other critical Twitter services. We subsequently explore how a topology self adjusts using back pressure so that the pace of the topology goes as its slowest component. Finally, we outline how Heron implements at most once and at least once semantics and we describe a few operational stories based on running Heron in production.
