Roaring Bitmaps 就是一种十分优秀的压缩位图索引,后文统称 RBM。压缩位图索引有很多种,比如基于 RLE(Run-LengthEncoding,运行长度编码)的WAH (Word Aligned Hybrid Compression Scheme) 和 Concise (Compressed ‘n’ Composable Integer Set)。相比较前者, RBM 能提供更优秀的压缩性能和更快的查询效率。 RBM 的用途...

Bitmap Index自诞生以来,产生了大大小小几十种变体,BBC、Concise、Roaring Bitmap等等。它们都是在原始的Bitmap Index上做了改进,使其所占内存空间更小。Bitmap已经是很精简的数据结构了,因此其发展方向,一般都是向着压缩二进制数组前进,在学术界形成一个研究分支:Bitmap Index Compression。
