Karthik Ramasamy is the engineering manager and technical lead for real-time analytics at Twitter. Karthik is the cocreator of Heron and has more than two decades of experience working in parallel databases, big data infrastructure, and networking. He cofounded Locomatix, a company that specializes in real-time stream processing on Hadoop and Cassandra using SQL, which was acquired by Twitter. Before Locomatix, he had a brief stint with Greenplum, where he worked on parallel query scheduling. Greenplum was eventually acquired by EMC for more than $300M. Prior to Greenplum, Karthik was at Juniper Networks, where he designed and delivered platforms, protocols, databases, and high-availability solutions for network routers that are widely deployed in the Internet. He is the author of several patents, publications, and one best-selling book, Network Routing: Algorithms, Protocols, and Architectures. Karthik has a PhD in computer science from UW Madison with a focus on databases, where he worked extensively in parallel database systems, query processing, scale-out technologies, storage engines, and online analytical systems. Several of these research projects were spun out as a company later acquired by Teradata.

Anomaly detection plays a key role in the context of analysis of real-time streams. This is exemplified by, say, detection incidents in real life from tweet storms. Arun Kejariwal and Karthik Ramasamy walk you through how anomaly detection is supported in real-time data streams in Heron—the streaming system built in-house at Twitter (and open sourced) for real-time computation.
