Clarification on how CloudWatch KEDA scaler calculates current metric value.

[bala-sophos]

I am exploring CloudWatch KEDA scaler and have a query around how CloudWatch KEDA scaler calculates current metric value.

If I set 'metricStatPeriod' to '300' (5 mins) and set 'metricCollectionTime' / 'metricEndTimeOffset' such that it denotes a 10 min interval, when the CloudWatch scaler queries CloudWatch it is going to get an array with two values, one for each 5 min period.

In this case how will the scaler determine the current metric value. Will it consider only one of the two values it got from CloudWatch ? Could someone clarify on this.

The scaler uses metricStat to specify how to aggregate multiple points.
