Apache NiFi
Apache NiFi is an open-source data integration platform designed to automate the flow of data between systems. It provides a web-based user interface for building, managing, and monitoring data pipelines with features like data provenance, security, and scalability. It is commonly used for ingesting, routing, transforming, and delivering data across diverse sources and destinations.
Developers should learn Apache NiFi when building real-time data ingestion pipelines, ETL (Extract, Transform, Load) processes, or handling data from IoT devices, logs, or APIs. It is particularly useful in scenarios requiring reliable data flow with built-in fault tolerance, such as in big data ecosystems, cloud migrations, or enterprise data integration projects where visual pipeline design and monitoring are critical.
