"An easy to use, powerful, and reliable system to process and distribute data"
Flow based programming system to automate data flow for ETL. It's not a full programming language, it's a collection of data processing modules. You can also execute script nodes (nifi expression language, python, javascript, ruby, lua, clojure, groovy. I think also any JVM language).
