Create FlowDebugger processor

The FlowDebugger processor allows a variety of Processor responses and failures to be simulated for testing, debugging, and troubleshooting the framework.

Responses it can produce on receipt of a flowfile include Transfer to Success, Transfer to Failure, Rollback without Penalty, Rollback and Yield, Rollback with Penalty, and Throw an Exception. The properties indicate how many times that response should be thrown, for example if configured with Success=10 and Failure=40, it will transfer the first 10 flowfiles to Success, transfer the next 40 to Failure, and then repeat.

Similarly, responses it can produce when triggered without a flowfile include Throw an Exception, Yield, and Return (do nothing).
