I have an audit file like :
Abc,123
Code,234
where the first column is the filename and second column is the record count of the file.
Now I have 2 such flow files with its filename and respective count, which I need to compare it with this audit file.
So somehow I need to first merge all the filenames and respective counts as an attribute
Open the audit file, split it and compare with this attribute for each of the files
How can I do that in Nifi?
