CUMSUM is missing in machine learning

Elastic Stack Elasticsearch
1

Dear,

For a project I'm using your machine learning part. Unfortunaletly I'm using a collumn with value +1,-1 and 0 which stand for people in a queue. I want to detect anomalies with the "high sum" function to detect when there are to many people in a queue, but I see when I'm using it he only take into account the amount of people who are coming in or leaving the queue on that particular moment without taking into account the past. Are guys gonna add the cumsum function in the future?

With kind regards, Amon De Keyser

Try the cumulative sum aggregation in ES, then have your ML job use the output of this aggregation (docs here, and a similar example here)
