Description

Currently, Doris Hyperloglog Error rate is2.44%, more specifically, in 99% cases, HLL error rate is under 2.44%.
In Meituan, some users say: "**we want a more accurate HLL!**we cannot tolerant such a high error rate"
Therefore, we intend to support a selectable error rate Hyperloglog like kylin.
