DATA PROCESSING METHOD AND APPARATUS

This application provides a data processing method and apparatus. In this application, a server obtains compressed data, where the data includes at least a first part and a second part. The server decompresses the first part, and decompresses the second part after decompressing the first part, where a popularity value of the first part is greater than a popularity value of the second part. Because the first part is sorted before the second part, the popularity value of the first part is greater than the popularity value of the second part, and a probability of accessing the first part is high, a read amplification ratio of decompressing the first part can be reduced, and an amplification ratio of decompressing the second part is approximately the same as that in an existing compression manner. Therefore, an average read amplification ratio of the server is reduced.
