Spark

http://spark.apache.org/

Apache Spark™ is a fast and general engine for large-scale data processing. Write applications quickly in Java, Scala, Python, R. Spark offers over 80 high-level operators that make it easy to build parallel apps. And you can use it interactively from the Scala, Python and R shells. Spark powers a stack of libraries including SQL and DataFrames, MLlib for machine learning, GraphX, and Spark Streaming. You can combine these libraries seamlessly in the same application.
