fx19880617 commented on issue #5153: different result on fasthll and distinctcounthll URL: https://github.com/apache/incubator-pinot/issues/5153#issuecomment-598991778 FastHll will convert one string into a hyperloglog object, which may represent thousand unique values. DistinctCountHLL treats string as a value, not hyperloglog object, so it will return the approximation of how many unique hyperloglog serialized strings, the value should be close to your total number scanned .
