Refining the art of query performance

Oct 26, 2014

Ever wonder how we power those “which controller went down today” queries that sprawl 1000s of databases, amounting to 100s of terabytes of log data every day? How do we deal with terabytes of data in a robust and efficient manner? We call it harmonic in memory query management.

We’ve been working with a distributed Cassandra cluster for almost a year. During that time, we have learned a bit about achieving scalability, and along the way we have collected some insight on achieving optimal query performance.
