I want to access the process group variable from execute script and then need to change its value. I am using python. I have read the article which describe how to access flowfile attributes but not variables. My requirement is when some job complete successfully then some value is to be stored in variable.

Hi @Vivek Singh

This is mainly on how to access.
To update the variable, you should use the API. I don't think there's a direct way from the script. Maybe take the output value as a flow file after the ExecuteScript and use another processor to call the API and update the value

I'd seen that already but its just for reading not for changing. I need to read and then manipulate the variable's value

more a question, so any update for manipulating variables? I have the same issue. Which API to call?
