I have an attribute which contains a list and I want to replace values with an incrementing value.
Variable1 = a,b,c
I'm able to count the number of value in the attribute using :
After getting the count I want to place as many $1,$2,$3......so on till it reaches the count. How can I do it?
For this I have used a python script to do the job but I wonder if it can be done with nifi expression langauge.
