Is there a mechanism or technique for communicating the results of a flow file to its "sister" flow files?
Here is a high-level description of what I am doing: Input to my flow is a JSON array of documents that get split (SplitJson) into individual documents and each document becomes a distinct flow file. Each document (flow file) gets validated against a JSON schema (ValidateJson) then gets updated into a Mongo collection (PutMongoUpdate). At the end of all this, I want to do some post processing but only if all documents processed successfully. When a failure occurs (either in the validation or the Mongo update) is there a way to communicate that to the success branch of the flow process so a decision can be made about whether to proceed to post processing or not. I am using NiFi 1.1.2 Thank you for any guidance you can offer, Steve
