虽然术语暗指二维数组的行和列,即矩阵,但是可以将这些次序推广到任何维度的数组:例如在 row-major order中,行索引变化最快,列索引变化最慢,推广到多个维度,就是其中沿着第一轴(维)的索引最慢,沿着最后一个轴(维)的索引最快。column-major则相反。 支持多维数组的编程语言或其标准库通常具有这些数组的行优先(主...
Whereas a traditional row-based store stores all attributes of one row together, followed by the attributes of the next row, and so on, a column-based stored uses one logical file per attribute (column) . The column-oriented layout makes it efficient to read just the columns you need for...
关于行式存储还是列式存储更适合于分析场景,本文在摘要部分就简明扼要的给出结论:列式存储(Column Stores)比行式存储(Row Stores)在性能上好过一个数量级!而这关键的原因就是:针对只读数据,I/O效率决定了这一切! 基于直观的认识,我们会认为在行式存储系统中,通过表结构垂直拆分(vertically partitioning)以及全列索...

This vertical arrangement allows for easy comparison and sorting of data based on the column's attribute. Whereas, a row represents a single record or entry, containing various attributes or fields of data horizontally. This facilitates understanding the relationship between different data points of ...
