Pig – a quick intro
Pig is MapReduce simplified. It is a combination of the Pig compiler and the Pig Latin script, which is a programming language designed to ease the development of distributed applications for analyzing large volumes of data. We will refer to the whole entity as Pig.
The high-level language code written in the Pig Latin script gets compiled into sequences of the MapReduce Java code and it is amenable to parallelization. Pig Latin promotes the data to become the main concept behind any program written in it. It is based on the dataflow paradigm, which works on a stream of data to be processed; this data is passed through instructions, which processes the data. This programming style is analogous to how electrical signals flow ...
