Data processing method and apparatus

A non-transitory computer-readable storage medium, storing instructions, wherein when the instructions are run on a computer, the computer is enabled to perform a data processing method comprising:

• obtaining a tiered storage feature and a data feature of first data, wherein the tiered storage feature comprises at least one of the following features:
• an importance, an access frequency, or a retention time, and the data feature comprises at least one of the following features:
• a data type, a data dimension, a data size, or a data content feature;
• determining a first compression algorithm based on the tiered storage feature and the data feature;
• and
• compressing the first data based on the first compression algorithm, to obtain compressed data, wherein the first data is data that has been compressed, and the compressing the first data comprises:
• decompressing the first data to obtain intermediate data;
• saving a first operation parameter used during the decompression;
• and
• compressing the intermediate data based on the first compression algorithm, to obtain the compressed data.

A computer device, wherein the computer device comprises a processor and a memory;

• the memory is configured to store computer program instructions;
• and
• the processor executes the computer program instructions in the memory to perform a method comprising:
