Slides: https://www.slideshare.net/DataStax/lambda-architecture-with-cassandra-vaibhav-puranik-gumgum-c-summit-2016 | Over the past year data at GumGum has quadrupled. Now a days we process 20 TB of new data every day. New data/reporting requirements pour in every week. Usage of the real time data is growing with the daily data. In this talk we are tying to answer the following questions: How do we serve real time data with daily batched data to our consumers together? What is Lambda Architecture and how does it help? What role does Cassandra play in Lambda Architecture at GumGum? How did we solve few bottlenecks in the architecture using Cassandra? How Cassandra can help you avoid microbatching and give you a true realtime data?
