Shark: Fast Data Analysis Using Coarse-grained Distributed Memory
Clifford Engle · 2013
Shark is a research data analysis system built on a novel coarse-grained distributed shared-memory abstraction. Shark marries query processing with deep data analysis, providing aunifiedsystemforeasydatamanipulationusingSQLand pushing sophisticated analysis closer to data. It scales to thousands of nodes in a fault-tolerant manner. Shark can answer queries 40X faster than Apache Hive and run machine learning programs 25X faster than MapReduce programs in Apache Hadoop on large datasets.
