DistinctCount queries are expensive, especially as selectivity decreases. Currently, this can degrade the overall performance across the table. One idea preventing overall perf degradation and pileup effect would be to switch internally to DistinctCountHLL for distinct values larger than a certain threshold. This would be better than simply truncating the collection of distinct values. -- This is an automated message from the Apache Git Service.
