How to make NiFi Controller Service to update periodically?
For more information:
We have two files 1. Student and 2. Class
Student file contains information like Reg_id, name, address.
Class contains information like Grade_id, Reg_id, date.
Both the files are coming on daily basis. We want to merge these two files in NiFi. For this purpose, we are using CSVRecordLookupService lookup service. But once the files are loaded, we do not see a way to reload it with new file received.
