anchorWithStickyNavbar_LWe7" id="背景">背景<a href="#背景" class="hash-link" aria-label="背景的直接链接" title="背景的直接链接"></a></h2><p>Doris 原有的 Bitmap 聚合函数设计比较通用，但对亿级别以上 bitmap 大基数的交并集计算性能较差。排查后端 be 的 bitmap 聚合函数逻辑，发现主要有两个原因。一是当 bitmap 基数较大时，如 bitmap 大小超过 1g，网络/磁盘 IO 处理时间比较长；二是后端 be 实例在 scan 数据后全部传输到顶层节点进行求交和并运算，给顶层单节点带来压力，成为处理瓶颈。</p><p>解决思路是将 bitmap 列的值按照 range 划分，不同 range 的值存储在不同的分桶中，保证了不同分桶的 bitmap 值是正交的。当查询时，先分别对不同分桶中的正交 bitmap 进行聚合计算，然后顶层节点直接将聚合计算后的值合并汇总，并输出。如此会大大提高计算效率，解决了顶层单节点计算瓶颈问题。</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="使用指南">使用指南<a href="#使用指南" class="hash-link"
