We have seen duplicates on a dataset in which the count got doubled. When checking on the query profile, the planning use Parallelism of 2 to read the same reflection which I assume is the cause of dups. Later when we query the dataset again, the parallelism showed ‘1’ and the dups were gone.
Attached please find the query profile. Thank you.
