I wonder if this could be related to "floating point error" error accumulation -- namely that floating point operations are approximations and can produce different values if executed in different order. Given operations like repartitoning and thread ordering, I don't think there is any guarantee that a particular operator will see the same data in the same order if the same query is run more than once 🤔 -- This is an automated message from the Apache Git Service.
