thank you Bryan.
is there documentation around for the variables?
If I add variables to the processor group and I want to reference a variable of the parent flow, will I have to add the scope somehow like ${scope.variable}?
If I have variables in different hierarchies of the flow with the same name, which one will be used?
P.S. I really like your blog :-)
Rgds,
Uwe

Hello,
You can use them in any fields that support _expression_ language, just
like variables in a properties file
(nifi.variable.registry.properties= in nifi.properties) or system
properties in bootstrap.conf.
In the properties file approach you had to restart NiFi for any
changes in the properties to be picked up.
In the new approach you no longer need to restart anything yourself,
it will be handled for you.
