Apache Pig

===========

Pig is a dataflow programming environment for processing very large files. Pig's

language is called Pig Latin. A Pig Latin program consists of a directed

acyclic graph where each node represents an operation that transforms data.

Operations are of two flavors: (1) relational-algebra style operations such as

join, filter, project; (2) functional-programming style operators such as map,

reduce. 

Pig compiles these dataflow programs into (sequences of) map-reduce or Apache Tez

jobs and executes them using Hadoop. It is also possible to execute Pig Latin

programs in a "local" mode (without Hadoop cluster), in which case all 

processing takes place in a single local JVM.
