Thanks Mike and Joe for the quick response. Hi Mike, Nifi is making api calls to source -> pull data -> Maps -> Post data to target via API. Generate flow file triggers the flow. Right now i manually run 1 process group after the previous one is complete. Hi Joe, The systems are the same. A and B. Just that i will be pulling different data set and that has to be done in sequence. Example, I will load customer followed by say order followed by items etc. The use case is one time data load from system A and B of different data sets that needs to happen in sequence. Trigger has to be only once to start the first one. Hope that helps.
