Thank you for your response and for performing a test with an HLL aggregator.

And, I should point out that for the current implementation of "TopN" if any
of the weight parameters are negative, the aggregations MUST be

I think we may have some confusion here. FIS uses `Identity` for the object
and `Comparable` for the weight parameter. And the
