Components of Apache NiFi
Apache NiFi UI has the following components −
User can drag the process icon on the canvas and select the desired processor for the data flow in NiFi.
Below icon is dragged to canvas to add the input port into any data flow.
Input port is used to get data from the processor, which is not present in that process group.
After dragging this icon, NiFi asks to enter the name of the Input port and then it is added to the NiFi canvas.
The below icon is dragged to canvas to add the output port into any data flow.
The output port is used to transfer data to the processor, which is not present in that process group.

A user uses below icon to add process group in the NiFi canvas.
After dragging this icon, NiFi asks to enter the name of the Process Group and then it is added to the NiFi canvas.
Remote Process Group
This is used to add Remote process group in NiFi canvas.
Funnel is used to transfer the output of a processor to multiple processors. User can use the below icon to add the funnel in a NiFi data flow.
This icon is used to add a data flow template to NiFi canvas. This helps to reuse the data flow in the same or different NiFi instances.
After dragging, a user can select the templates already added in the NiFi.
These are used to add text on NiFi canvas about any component present in NiFi. It offers a range of colors used by a user to add aesthetic sense.
