Tech: Clojure, Java, Hadoop

ElephantDB is a distributed database specialized for serving key-value data exported from Hadoop. It fills the gap between batch computation and low-latency reads, letting you compute huge datasets with MapReduce and serve them directly without a traditional database layer. I maintained the project and contributed the Cascalog integration and Thrift service layer.
