I successfully followed this Microsoft guide: How to extract key phrases in Text Analytics
Next day, I opened Query Editor to add an Index column. When I applied the change, it appears that the custom function to extract key phrases re-runs. I get this impression because Power BI is connecting to the API endpoint.
Re-running the custom function in not necessary - no new text was added. All it does is increase the time it takes to add a simple index column. Worse though is that it adds to my API usage.
Is my understanding as set out above correct?
If yes, how do I prevent the custom function from re-running?
Ideally, I only want the custom function to run on new data that I add to the data set. Is this possible?
If my understanding is incorrect, then why does Power BI connect to the API endpoint?
Thanks
Duffy
