Apache NiFi describes itself as “an easy-to-use, powerful, and reliable system to process and distribute data.” [1] In simple terms, NiFi implements a web-based interface to define how data is moved from a source to a destination. Users may define various “processors” to manipulate data along the way. This is often needed when processing business data or preparing data for machine learning. A dataset used for machine learning may arrive in one format (let's say JSON), but to conveniently use it for training, it must be converted to JSON or inserted into a database. The features are not just attractive to machine learning, but many business processes require similar functionality.
