Abstract: Approaches for structuring a plurality of page images in-memory are described in various examples of the present disclosure. In one example, a unique page identifier provided within a reference page image is identified. The unique page identifier is associated with a target page image stored in-memory. Once identified, the page identifier associated with the target page image is replaced with a location specific identifier of the target page image, wherein the location specific identifier is based on an in-memory location of the target page image.

Abstract: A technique includes acquiring a plurality of write requests from at least one memory controller and logging information associated with the plurality of write requests in persistent storage. The technique includes applying the plurality of write requests atomically as a group to persistent storage.

Abstract: A method for mapping virtual memory pages to physical memory pages is described. The method includes receiving a mapping of a virtual memory page to multiple physical memory pages, detecting a request for a transaction to be performed on data contained in the multiple physical memory pages, in which the transaction includes a number of data updates, determining which of the number of multiple physical memory pages contains a latest version of the data to be updated by the transaction, updating a physical memory page by performing the transaction within a physical memory page among the multiple physical memory pages that does not contain the latest version of the data, and updating an indication of which of the physical memory pages contains the latest version of the data pertaining to the transaction.
