Abstract
In an example embodiment, one or more pages from a database are stored in a page cache stored in a shared memory, the one or more pages stored in a packed format. One or more rows from the database are stored in a row cache stored in the shared memory, the one or more rows stored in an unpacked format. A request for a row of the database is received. Then, the row cache is searched for the row. In response to a determination that the row cannot be found in the row cache, the page cache is searched for the row. Finally, the row is returned.
