Hello everybody,
a bit of context:
I'm currently parsing a json in Nifi using a RouteOnAttribute component like this :
${stationName:equals("value 1") :or(${stationName:equals("value 2")}) :or(${stationName:equals("value 3")}) :or(${stationName:equals("value 4")}) :or...
I have more than 20 values to test, it works well but I would like to make something dynamic, something more readable... And by the way if the list of values changes I dont wanna re write everything again.
What i'm doing :
All theses values are stored in a csv file in S3, I made a job that download this file, filter the right values to keep... Here is my job:
At the end, in the LogAttribute processor I can see my values:
From this point, how can I convert this list of values in a variable that will looks like:
${stationName:equals("Rockware Avenue / Greenford Station") :or(${stationName:equals("Oldfield Lane South")}) :or(${stationName:equals("Ash Grove")}) :or(${stationName:equals("Telford Road")}) :or...
The idea is to call this variable in the RouteOnAttribute processor later.
I tried to use a ExecuteScript processor but my code is not working, maybe there is something easier to do ?
Thanks for your help,
Regards,
Thomas
