For each of a sequence of commits of the data, the data is represented by identifying pages of the data that have changed since a prior commit in the sequence of commits. A sparce file is formulate for the commit, and contains each of identified pages, and for each identified page a mapping of the identified to a page address of the identified page in the address range. The sparce file is then stored as associated with the corresponding commit. Thus, an ordered sequence of sparce files can be created and layered on top of a base file that represents the entire page address range. The sparce files may be quite small as there may be relatively few pages (or perhaps even no pages) that changed since the prior commit in the sequence of commits. Reads occur by creating a sparce in-memory object, and checking for each page at each sparce."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Layered memory mapped file technology","description":"Rapid writing to and reading from even very large amounts of data, especially where the data evolves more slowly over time.
