The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for execution by a record processing and storage system includes receiving a plurality of records and corresponding row numbers. Pages are generated from the received records. Page metadata is generated for each page that includes row number span data based on row numbers of the records included in each page. Pairs of pages are identified in the plurality of pages based on having row number span data in their page metadata that include a row number span overlap. For each pair of pages, row number span data is updated for a first page in the pair by removing the row number span overlap with a second page in the pair. Reads of pages are performed based on their row number span data. Only records of each first page of each pair of pages having row numbers that are within the updated row number span data are read.”
