What is NiFi?
Apache NiFi is a distributed system dedicated to extracting, transforming, and loading data (ETL).
It is Open Source and is developed and maintained by the Apache Software Foundation.
How does it work?
One of the strongest points of NiFi is the ability to program data flows by dragging and connecting the necessary components on the canvases of the administration website.
It is therefore not necessary to have specific programming knowledge, but rather to understand and correctly configure each of the components that you want to use.
