HLL++ is probabilistic and may under/over-estimate. The randomized test now allows 10% or ≥1 deviation between approximate and exact cardinality. Removed the prior 10% upward bias in NoDictColumnStatisticsCollector.getCardinality() to avoid systematic overestimation and reduce flakiness. -- This is an automated message from the Apache Git Service.
