DaimonPl opened a new issue #4617: Configurable HyperLogLog accuracy URL: https://github.com/apache/incubator-druid/issues/4617 Even though current algorithm claims to be "98% right" we've found that error is sometimes even around 4-5% Idea is to have ability to increase accuracy (at the cost of speed and space) for such cases. I assume that for proper estimation entire datasource would need to be aggregated with same accuracy setting Is number of buckets proper candidate for accuracy prameter?
