Abstract

The invention discloses a data compression method. The data compression method comprises the following steps: splitting Postgresql Numeric data into a plurality of field files according to a format of a Postgresql Numeric data type; performing differential remapping on each field file to obtain a cardinal number file, a cardinal number index file and a difference value file corresponding to each field file; and performing huffman coding on the cardinal number files, the cardinal number index files and the difference value files corresponding to all the field files to obtain a compressed file. According to the data compression method and device, the data are split into the field files according to the format of the data type, similar data are compressed, and finally, huffman coding is further performed to obtain the compressed file, so that the compression rate of data compression is increased, and the utilization rate of hardware resources is increased. The invention further discloses a data compression device, a server and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data compression method, a data compression device, a server, and a computer-readable storage medium. Background technique [0002] With the advent of the data age, the data generated by all walks of life is increasing exponentially. The generation of large-scale data needs to consume a lot of storage space. Compressing data is often an effective way to reduce the storage space occupied. [0003] In related technologies, the general compression algorithm processes data based on bytes, without considering the physical meaning of the data format, but simply splits the data into bytes for processing, and does not make full use of the storage structure of specific data types characteristics, so that the compression effect of specific data types is not ideal, reducing the compression effect of data, that is, the compression rate of data cannot be maintained.
