- [[http://incubator.apache.org/pig/|Apache Pig]] is a platform for analyzing large data sets. Pig's language, Pig Latin, lets you specify a sequence of data transformations such as merging data sets, filtering them, and applying functions to records or groups of records. Pig comes with many built-in functions but you can also create your own user-defined functions to do special-purpose processing.

  Pig Latin programs run in a distributed fashion on a cluster (programs are complied into Map/Reduce jobs and executed using Hadoop). For quick prototyping, Pig Latin programs can also run in "local mode" without a cluster (all processing takes place in a single local JVM).

- '''Pig Has Grown Up!'''. On 10/22/08 Pig graduated from the [[http://incubator.apache.org/|Incubator]] and joined [[http://hadoop.apache.org/|Apache Hadoop]] as a subproject.

- '''Pig is Getting Faster!'''  2-6 times faster, for many queries.  We've created a set of benchmarks and run them against the pig 0.1.0 release (modified to run on hadoop 0.18) and against the current trunk (previously `types` branch.) Joins and order bys in particular made large performance gains. For complete details see PigMix.

- '''Interested in Pig Guts?''' We are completely redesigning the Pig execution and optimization framework. For design details see PigOptimizationWishList and PigExecutionModel.
