  • Data compression/decompression device
    Patent number: 10116325
    Abstract: When compressing an arrangement of fixed-length records in a columnar direction, a data compression device carries out data compression aligned with the performance of a data decompression device by computing a number of rows processed with one columnar compression from the performance on the decompression device side, such as the memory cache capacity of the decompression device or the capacity of a primary storage device which may be used by an application, and the size of one record. Thus, while improving compression ratios of large volumes of data, including an alignment of a plurality of fixed-length records, decompression performance is improved.
