Abstract

The embodiment of the invention provides a data compression method, an electronic device and a computer readable storage medium. In the embodiment of the invention, for the time sequence data generated in a certain time period, a target compression algorithm is selected from a plurality of compression algorithms according to the time-varying characteristics of the time sequence data, and then thetarget compression algorithm is utilized to compress the time sequence data to obtain compressed data. Therefore, the compression algorithm can be flexibly selected in the data compression process, different compression algorithms are adopted for data with different time-varying characteristics, the flexibility is higher, and the compression ratio can be increased.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data compression method, electronic equipment, and a computer-readable storage medium. Background technique [0002] In some application systems, a large amount of time-related data will be generated, such as log data during system operation, central processing unit (Central Processing Unit, CPU) utilization at different times, and commodity order quantities at different times. As time goes by, these data will increase and will take up more storage space. [0003] In the prior art, generally, a compression algorithm is used to compress and store the time-related data, thereby reducing the occupied storage space. The existing methods for compressing time-related data are not flexible enough, and the compression ratio is low. Contents of the invention [0004] Various aspects of the present application provide a data compression method, an electronic dev...
