Hi, I’m not sure I fully understand the question, as you say that “customers” have attributes, but I was under the impression that the customers were various processors/“endpoints”. Flowfiles are the atomic units of data passing through the flow, and that is where attributes are stored.
Regardless, to perform complex string comparisons, I believe your best option is an ExecuteScript processor. In any of the supported languages, you can quickly parse the attributes into collections (i.e. java.util.List) via String split on delimiter, perform set arithmetic (A - B), and then route based on the results.
