In a row store, or row oriented database, the data is stored row by row, such that the first column of a row will be next to the last column of the previous row.For instance, let’s take this Facebook_Friends data:This data would be stored on a disk in a row oriented database...

从最终的实验得出,在行式存储上就算以column-oriented方式来设计数据的物理结构,面对分析型场景还是无法与列式存储抗衡。面对分析型场景,列式存储在本质上优于行式存储。这同时又提出一个新问题: Which of the many column-database specific optimizations proposed in the literature are most responsible for the si...
