What is Apache NiFi?

Editorial review
NiFi automates data flows with a visual interface. Drag sources, processors, and destinations onto a canvas, connect them, and watch data move between systems without writing code. Built-in processors handle common transformations-filter, route, enrich, convert formats. Data provenance tracks every byte through the system for debugging and compliance. Back pressure prevents downstream systems from being overwhelmed. When data integration involves many sources and complex routing logic, NiFi's visual approach makes flows comprehensible that would be unmanageable in code.
