Apache Pig: It goes to 0.11

Apache Pig: It goes to 0.11

From the post:

After months of work, we are happy to announce the 0.11 release of Apache Pig. In this blog post, we highlight some of the major new features and performance improvements that were contributed to this release. A large chunk of the new features was created by Google Summer of Code (GSoC) students with supervision from the Apache Pig PMC, while the core Pig team focused on performance improvements, usability issues, and bug fixes. We encourage CS students to consider applying for GSOC in 2013 — it’s a great way to contribute to open source software.

This blog post hits some of the highlights of the release. Pig users may also find a presentation by Daniel Dai, which includes code and output samples for the new operators, helpful.

And from Hortonworks’ post on the release:

  • A DateTime datatype, documentation here.
  • A RANK function, documentation here.
  • A CUBE operator, documentation here.
  • Groovy UDFs, documentation here.

If you remember Robert Barta’s Cartesian expansion of tuples, you will find it in the CUBE operator.
