The abstract of the patent published by the U.S. Patent and Trademark Office states: “One or more embodiments of the present specification provide disk storage-based data reading methods, apparatuses, and systems. A data reading instruction sent by a client device is received. The data reading instruction includes a service attribute. Location information corresponding to the service attribute is obtained from a pre-stored index table. The location information includes block heights and offsets of data blocks in which one or more data records are located. A block height sequence is generated by sequentially arranging the block heights. Mutually exclusive continuous block height intervals are determined from the block height sequence. One or more target data blocks are read corresponding to a block height interval from a disk. The one or more data records are obtained by querying the one or more target data blocks based on the location information, and returned to the client device.”
