> Currently indexes are created with the same row format as the table. However, indexes can be created in aligned row format independent of the table because the columns in the index table doesn't have any other column other than salt, index columns, and primary key of the table. These column values constitute the rowid. Index rows are always deleted and inserted and are never updated. Hence, it goes well to create index in aligned row format. In addition, index in aligned row format has the following advantages:
> - Reduced storage space for the index
> - Reduced block cache and memstore space at runtime
