configuration variables?
I have several processors in my flow using the same database url parameter. Is there any method in Nifi to read configuration parameter(s) from Zookeeper, or similar?
Thank you,

The variable registry is hierarchical, so variables defined in a
parent group will be visible to all children, unless a child group has
a variable with the same name which will override the parent's value.
So you can put any common variables in the root group.

What's about level higher - common variables for several process groups?
Thanks.
