What is pangool?

Pangool is a Java-based library that simplifies the process of writing MapReduce jobs in Hadoop. It provides a set of convenient data structures and utilities that reduce the amount of boilerplate code needed to manipulate data in the MapReduce framework. By using Pangool, developers can focus on the business logic of their application, rather than worrying about the lower-level details of the Hadoop API.

Some key features of Pangool include:

• A simple, fluent API for defining data schemas and transformations
• Support for rich data types like maps, arrays, and nested records
• Integration with popular Hadoop APIs like Writable and Avro
• MapReduce-friendly partitioners and serialization formats
• Parquet integration for efficient, columnar data storage

Overall, Pangool aims to make it easier for developers to write high-quality, maintainable MapReduce code that can scale to large datasets.
