Tech Talk: Eric Tschetter on Druid - Distributed Exploration of High Dimensional Data
Druid is a distributed system in use at Metamarkets (http://www.metamarkets.com) to facilitate rapid exploration of high dimensional data. They use Druid to expose impression monetization data to internet publishers along any arbitrary combination of demographic, content and sales-based dimensions. One Druid cluster currently exposes a data set of >15 billion rows of data representing >500 billion impressions in hypercubes of varying dimensionality (largest is 28 dimensions) while allowing for exploration using top lists and timeseries in sub-second latencies. The tech talk will be a discussion of the design considerations and architecture of the system.
