%description
Pig is a platform for analyzing large data sets that consists of a high-level language
for expressing data analysis programs, coupled with infrastructure for evaluating these
programs. The salient property of Pig programs is that their structure is amenable
to substantial parallelization, which in turns enables them to handle very large data sets.
At the present time, Pig's infrastructure layer consists of a compiler that produces
sequences of Map-Reduce programs, for which large-scale parallel implementations already
exist (e.g., the Hadoop subproject). Pig's language layer currently consists of a textual
language called Pig Latin, which has the following key properties:
* Ease of programming
It is trivial to achieve parallel execution of simple, "embarrassingly parallel" data
analysis tasks. Complex tasks comprised of multiple interrelated data transformations
are explicitly encoded as data flow sequences, making them easy to write, understand,
and maintain.
* Optimization opportunities
The way in which tasks are encoded permits the system to optimize their execution
automatically, allowing the user to focus on semantics rather than efficiency.
* Extensibility
Users can create their own functions to do special-purpose processing.
