Hi, I am still learning Apache NiFi but I need a quick solution for triggering a processor in a process group after the first process group finished processing. I have two process groups and two of them extracting, little bit transforming and loading tables from source db to destination db. In both process group, the process starts with GenerateTableFetch processor. What I want to do is after first process group finished its work the second one start processing. I managed to configure process groups so that second one is wating the first one to finish all its process. But how can I manage to prevent the first one to transfer data to second processor? I don't need the data anymore after I put it to destination but I need to trigger second process as well.

Thank you Samsal. I have tried different combinations but I am suprised I did not try this one. This is javascript syntax, right? If I learn beginner level javascript, is it going to be easier to use NiFi's expression language?
