The accumulators add non-finite values into the running sum and subtract them when they leave. Subtracting infinity from infinity produces NaN, and subsequent updates or retractions cannot recover a finite sum. The non-distinct Float64 sliding accumulators now share a finite sum and separate counts for NaN, positive infinity, and negative infinity. https://github.com/apache/datafusion/pull/26784 -- This is an automated message from the Apache Git Service.
