Netflix Keystone - Real-time Stream Processing Cloud Service


The need for gleaning answers from data in real-time from unbounded data streams is moving from nicety to a necessity. Netflix is a data driven company and Netflix Keystone Stream Processing Service processes over a Trillion messages a day with at-least once processing semantics in the cloud to derive insights.

To ease extracting intelligence from unbounded streams easily we are building a multi-tenant, self-serve, real-time event processing service infrastructure so that the user can focus on extracting value and not have to worry about building infrastructure. We will share our experience
