Eric Tschetter is the lead architect of Druid, Metamarkets’ distributed, in-memory database. Prior to joining Metamarkets, he held senior engineering positions at Ning and LinkedIn. At LinkedIn, Eric productized LinkedIn’s People You May Know with Hadoop. He holds bachelors degrees in Computer Science and Japanese from the University of Texas at Austin, and a M.S. from the University of Tokyo in Computer Science.
His talk will focus on the design considerations and architecture of Druid, an open-source, scalable, real-time analytical data store. Druid is in use at Metamarkets (http://www.metamarkets.com) to facilitate rapid exploration of high dimensional spaces. We use Druid to expose impression monetization data to ad tech companies along any arbitrary combination of demographic, content and sales-based dimensions. One Druid cluster currently exposes a data set of >50 billion rows of data representing >2 trillion impressions in hypercubes of varying dimensionality (largest is 30+ dimensions) while allowing for exploration using top lists and timeseries in sub-second latencies.
