Hello team! what’s the hyperLogLog algorithm that Pinot used in distinctCountHLL? is it hyperLogLog or HyperLogLog++ ?

It is using com.clearspring.analytics.stream.cardinality.HyperLogLog - https://github.com/apache/pinot/blob/master/pinot-segment-local/src/main/java/org/[…]t/segment/local/aggregator/DistinctCountHLLValueAggregator.java

thanks @Soumitra Kumar
