Hi - I have a requirement to read one message off RabbitMQ and fully process that message before I take another message off the queue. I found some great guidance to setting up a 'traffic light' pattern here (https://gist.github.com/ijokarumawak/9e1a4855934f2bb9661f88ca625bd244), but it won't work for my process because the Notify will get triggered by the GenerateFlowFile before the long-running process triggers, which will put two or more messages into the process at once. The documentation for Notify makes reference to using a 0 value in Signal Counter Delta to simulate 'open-close-gate' flow control, which sounds like what I'm looking for. Can someone point me in the right direction?
Thanks, Dave
