Apache Pig =========== Pig is a dataflow programming environment for processing very large files. Pig's language is called Pig Latin. A Pig Latin program consists of a directed acyclic graph where each node represents an operation that transforms data. Operations are of two flavors: (1) relational-algebra style operations such as join, filter, project; (2) functional-programming style operators such as map, reduce. Pig compiles these dataflow programs into (sequences of) map-reduce jobs and executes them using Hadoop. It is also possible to execute Pig Latin programs in a "local" mode (without Hadoop cluster), in which case all processing takes place in a single local JVM.

Incubator Disclaimer ===================== Apache Pig is an effort undergoing incubation at The Apache Software Foundation (ASF). Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
