----------------------------------------------------------------
Please add this feature, preferable in a point release and not in a too distant
future. This is painful experience. I have flows that I re-use for different
data sources/targets, which I previously used variables to configure. When I
copied the process group, the variables would copy and I could then change them
as needed. Now, I have updated then to use parameters, which I find more
useful especially for sensitive values and for processor/controller properties
that do not support Expression Language. Unfortunately, now that the parameter
context is separate from the process group, I have to manually create a copy of
the parameter context, which has 56 parameters.
You could add a copy/paste function to the NiFi Parameter Contexts window, add
a 'Save As' to the Update Parameter Context window, or have an export/import
feature allowing you to save/load the parameters to disk, possibly in a json
format.
Note, I would expect a copy/export feature would copy all parameter values,
with the exception for any sensitive parameters.
BTW, I found mentioned in related feature proposal this copy feature, "When
creating a new Parameter Context, the user should be given ability to create a
new, empty Context or copy an existing Context that they have READ permissions
to. This makes it far easier to design a flow, then deploy several instances of
the flow, in which each instance has mostly the same parameters but slightly
different." See
