Apache Pig Day 1

Hello People,
I increasingly spending more time working on pig. (Thankgod).
This experience has been very valuable as it has increased my knowledge on data.
Pig is an open source project.
Language for developing pig scripts is called pig latin.
Its easier to write pig script than mapreduce code (Its saves the developers time)
Pig is a dataflow language that means it allows the users to describe data.
Pig Latin Scripts are describes a DAG. Directed Acyclic Graph
Developed by Yahoo!.
Aim to this language is to find a sweet spot between SQL and Shell Scripts.
To sum it up Pig is you to build data pipelines / run ETL workloads.
