Apache Pig 0.13.0

A dataflow programming environment for processing very large files
Apache Pig is an open source and free 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 Apache 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, Apache 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).

Apache 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.

Apache Pig is cross-platform and it works on Mac OS X, Windows and Linux.

What's New in This Release:
  • This release includes several new features such as pluggable execution engines (to allow pig run on non-mapreduce engines in future), auto-local mode (to jobs with small input data size to run in-process), fetch optimization (to improve interactiveness of grunt), fixed counters for local-mode, support for user level jar cache, support for blacklisting and whitelisting pig commands.
  • This also includes several performance fixes and debuggability features.
  • A few non-backwards compatible interface modifications have been introduced in this release to make pig work with non-mapreduce engines (eg- PigProgressNotificationListener).
