Abstract

The invention relates to the technical field of big data, and discloses a data compression method, device and equipment and a computer readable storage medium. The method comprises the steps of obtaining to-be-compressed data, and classifying the to-be-compressed data; identifying the classified to-be-compressed data, and determining a label with numeric data, a numeric value and a label without numeric data, the label comprising a label prefix and a label subscript; compressing the label subscripts with the numeric data and the numerical values; querying the label prefixes of the to-be-compressed data, and judging whether continuous to-be-compressed data with the same label prefix exists or not; if not, inserting a second preset symbol between the label prefix and the compressed label subscripts; and obtaining compressed data based on the label prefix, the second preset symbol and the compressed label subscript, or the label prefix, the second preset symbol, the compressed label subscript and the compressed numerical value, and outputting the compressed data. According to the invention, the data compression rate is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data compression method, device, equipment, and computer-readable storage medium. Background technique [0002] Data compression is a technical method to reduce the amount of original data to reduce storage space and improve its transmission, storage and processing efficiency without losing useful information. In the prior art, a string compression algorithm is usually used when compressing original data. At present, the most commonly used string compression algorithm generally compresses strings in which the same characters appear continuously. For example, if the string to be compressed is aabccccaaa, it will be a2b1c4a3 after compression. The application range of this compression method is very narrow, and the compression ratio is also limited. For large-scale projects that store hundreds of millions of levels of data, the compression ratio is far from...
