Store JSON in Cassandra the Hard Way

For this meetup we are excited to be joined by Josh Dzielak, VP of Engineering at Keen IO!

What You'll Learn At This Meetup

Josh designed and built the distributed event data backend that powers Keen IO's real-time analytics API. The system, based on Storm and Cassandra, is capable of running ad-hoc queries over billions of JSON events in seconds. In this talk, Josh will describe the data model that makes this possible and contrast it with a few that didn't work out. The talk will conclude with a few lessons learned from running Storm and Cassandra in production for over 9 months.
