For this meetup, we are excited to be joined by Dave Josephsen, Developer Evangelist over at Librato to share his experience with data storage and how Librato uses Cassandra.
What You'll Learn at this Meetup:
Librato runs a distributed multi-tenant time-series data storage, analysis, and alerting platform as a service. In this talk we describe our internal data processing and storage infrastructure, which relies heavily on Apache’s Storm and Cassandra projects to process over 200,000 writes per second and store nearly 10 billion data samples. We give infrastructure details, recounting our initial design decisions as well as various scaling challenges that have forced us to refactor our storage designs. Finally we live-demo our storage infrastructure dashboards and relate the system and application metrics that we’ve found useful in monitoring Cassandra for performance and reliability.
We hope to see you there!
