METHODS, APPARATUSES AND COMPUTER PROGRAM PRODUCTS FOR GENERATING INDEXES USING A JOURNAL IN A KEY VALUE MEMORY DEVICE

摘要

An apparatus for generating indexes of data may include a processor and memory storing executable computer code causing the apparatus to at least perform operations including obtaining an order number responsive to receipt of a request from a device to index an item(s) of data. The computer program code may further cause the apparatus to map the order number to a key value and link the key value to the data and provide one or more index entries to a memory device to enable storage of the index entries. The index entries may include information corresponding to the key value and the data. The computer program code may further cause the apparatus to assign a new index row(s) including the data for inclusion in a set of index rows of a designated partition(s) to obtain a built index(es) of the data. Corresponding methods and computer program products are also provided.
