Karthik Ramasamy
Cofounder and CEO, Streamlio


Karthik is the engineering manager and technical lead for Real Time Analytics at Twitter. He has two decades of experience working in parallel databases, big data infrastructure and networking. He cofounded Locomatix, a company that specializes in real timestreaming processing on Hadoop and Cassandra using SQL that 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. Before joining Juniper at University of Wisconsin, he worked extensively in parallel database systems, query processing, scale out technologies, storage engine and online analytical systems. Several of these research were spun as a company later acquired by Teradata.

He is the author of several publications, patents and one of the best selling book “Network Routing: Algorithms, Protocols and Architectures.” He has a Ph.D. in Computer Science from UW Madison with a focus on databases.

Modern enterprises are data driven and want to move at light speed. To achieve real-time performance, financial applications use streaming infrastructures for low latency and high throughput. Twitter Heron is an open source streaming engine with low latency around 14 ms. Karthik Ramasamy and Supun Kamburugamuvee explain how they ported Heron to Infiniband to achieve latencies as low as 7 ms. Read more.

In a series of three 11-minute presentations, key members of Apache Kafka, Heron, and Apache Apex discuss their respective implementations of exactly once delivery and semantics. Read more.
Karthik Ramasamy (Streamlio)
Twitter processes billions of events per day at the instant the data is generated. To achieve real-time performance, Twitter employs Heron, an open-source streaming engine tailored for large-scale environments. In this talk, Karthik will present the techniques used by Heron to implement exactly once and share the operating experiences at scale.
