Handling files using NiFi processors

In the previous sections, you learned how to read and write CSV and JSON files using Python. Reading files is such a common task that tools such as NiFi have prebuilt processors to handle it. In this section, you will learn how to handle files using NiFi processors.

Working with CSV in NiFi

Working with files in NiFi requires many more steps than you had to use when doing the same tasks in Python. There are benefits to using more steps and using Nifi, including that someone who does not know code can look at your data pipeline and understand what it is you are doing. You may even find it easier to remember what it is you were trying to do when you come back to your pipeline in the future. Also, changes to the data pipeline do not require refactoring a lot of code; rather, you can reorder processors via drag and drop.

In this section, you will create a data pipeline that reads in the data.CSV file you created in Python. It will run a query...
