Pig is an extensible platform for analyzing large datasets that allows both local and MapReduce execution. It features a simple language called Pig Latin for loading, filtering, transforming, and storing data. Pig Latin scripts can be debugged using commands like DUMP, DESCRIBE, EXPLAIN, and ILLUSTRATE and allows working with data through operations like FILTER, FOREACH, GROUP, UNION, and SPLIT.
