Abstract:
A logical page identity for a logical page containing data storage application data can be mapped to a physical storage page location in a storage where the data of the logical page are stored. The mapping as well as additional page data can be retained within a persistence layer accessible to the data storage application. The additional page data can include at least one of a size of the page and a next page linkage indicating a second page that follows the page in a page sequence of related pages. The retained mapping and additional page data can be retrieved from the persistence layer to initiate a page operation on the related pages, and the page operation can be executed on the related pages based on the retrieved mapping and additional page data. Related methods, systems, and articles of manufacture are also disclosed.
