Abstract
The present disclosure relates to a system and methods of implementing an integer-value database using a single I/O operation. In particular, the present disclosure relates to methods of writing and reading information to a database using key/value pairs, including receiving, at a database management system, a value to be written to a database, the database including a plurality of segments stored on a storage medium, and assigning, by the database management system, an assigned key to the value based on keys previously used in the database. The method may further include storing, by the database management system, the assigned key and the value to a segment at a virtual end of the database, wherein the segment is identified in a mapping index by an offset and the mapping index identifies a first key in the segment, and returning the assigned key.
