From YouTube: C* Summit 2013: Time-Series Metrics with Cassandra

Description

Speaker: Mike Heffner, Engineer & Co-Founder at Librato
Slides: https://speakerdeck.com/mheffner/time-series-metrics-with-cassandra
Librato's Metrics platform relies on Cassandra as its sole data storage platform for time-series data. This session will discuss how we have scaled from a single six node Cassandra ring two years ago to the multiple storage rings that handle over 150,000 writes/second today. We'll cover the steps we have taken to scale the platform including the evolution of our underlying schema, operational tricks, and client-library improvements. The session will finish with our suggestions on how we believe Cassandra as a project and its community can be improved.
