Answer Posted / Ramendr Tiwari
Column Storage and Row Storage are two storage concepts in SAP HANA. In Column Storage, data is stored vertically (i.e., all columns of a table share the same storage space). This approach helps in optimizing queries that filter on a specific column, as it reduces I/O operations. On the other hand, Row Storage stores data horizontally (i.e., each row occupies its own space). It is useful for tables with small numbers of columns and large volumes of data, as it provides faster read performance.
