Pig Performance and Optimization Analysis by Li Jie.
From the post:
In this post, Hortonworks Intern Li Jie talks about his work this summer on performance analysis and optimization of Apache Pig. Li is a PhD candidate in the Department of Computer Science at Duke University. His research interests are in the area of database systems and big data computing. He is currently working with Associate Professor Shivnath Babu.
If you need to optimize Pig operations, this is a very good starting place.
Be sure to grab a copy of Running TPC-H on Pig by Li Jie, Koichi Ishida, Xuan Wang and Muzhi Zhao, with its “Six Rules of Writing Efficient Pig Scripts.”
Expect to see all three of these authors in DBLP sooner rather than later.
