Row storage

Column storage

Row storage, with its sequential arrangement of data records, is particularly useful in OLAP and analytical tasks where data aggregation and precise column selection are paramount. On the other hand, columnar storage shines in managing precomputed metrics due to its improved performance, superior compression rates, and potential for better-informed decision-making during query execution.
