Nifi dataflow trigger another flow or process

[#1]

Hi,

I have a flow that i need to kick off some sql to run when it is done. Trying to avoid timing or scheduling it. Its just a querydbtable, and then putdbrecord from one db to another. If when all flowfiles are done processing, i could let this thing start, that would be ideal. having a hard time understanding how to use wait and notify to do this. I've read a few articles including this one: http://ijokarumawak.github.io/nifi/2017/02/02/nifi-notify-batch/

Thanks for any help,

Ron
