I have different input files for different sources. Can I create a common Nifi flow which processes all the different kind of files? Each files will be having different types of columns and different types of output table to be loaded. For example, File 1 will be having column A, Column B to be loaded to Table AB, File 2 will be having column C, Column D, Column E to be loaded to Table CDE. Can I achieve this in a single flow or should I create different flows for different types of files?
