Speakers: Shreeganesh Ramanan and Mike Davis (Optimizely) Pushing well past MongoDB's limits (2TB data every week) is an interesting exercise in operational frustration. It also severely hampers flexibility of design for new use cases. This talk covers the architectural journey from MongoDB/Redis to HBase at Optimizely -- including the performance, design flexibility, speed of implementation, and other gains made. It also covers the operational setup needed to monitor and maintain the system as well as lessons learned from the migration process itself.
