columnar storage

Columnar storage is a way of organizing data in a database where each column's entire data set is stored together, rather than storing complete rows. This approach makes it faster and more efficient to analyze specific data points across many records, especially for tasks like reporting or data analysis, because it reduces the amount of data that needs to be read and processed. By focusing on one column at a time, systems can quickly retrieve relevant information without loading unnecessary data, leading to improved performance for read-intensive operations.
