Column Vs Row Storage at Amelia Cunningham blog

Column Vs Row Storage. The fundamental difference lies in how data is laid out on disk: A columnar database stores data grouped by columns rather than by rows, optimizing performance for analytical queries. Each column contains data of the same type, allowing for efficient compression. In the intricate landscape of data storage, the choice between row and column storage is far from arbitrary. If the data you need to access is stored mostly in a small number of columns and it is not necessary to query each field in the rows, you may be better off with a columnar. Let’s look at the same data set again and see how it would be stored in a column oriented database. Columnar databases organize data by column/field, making aggregating data and performing calculations easier. And because a query needs to access only relevant columns, the design enhances data retrieval speed.
