Presentation: Events storage and analysis with Riak at

Track: Solutions Track Thursday / Time: Thursday 11:30 - 12:20 / Location: Verwey Kamer

At, we have a constant flow of events coming from various applications and internal subsystems. This critical data needs to be stored for real-time, medium and long term analysis. Events are schema-less, making it difficult to use standard analysis tools.This presentation will explain how we built a storage and analysis solution based on Riak. The talk will cover: data aggregation and serialization, Riak configuration, solutions for lowering the network usage, and finally, how Riak's advanced features are used to perform real-time data crunching on the cluster nodes.
