Data Processing Method and Apparatus, Device, and Computer-Readable Storage Medium

A computing device cluster, comprising:

• one or more computing devices configured to:
• obtain a data processing instruction to decompress first compressed data to obtain target data, wherein the first compressed data comprises a compressed data group, wherein the compressed data group comprises the target data, and wherein the data processing instruction comprises a first start location of the target data in the data group and a first length of the target data;
• determine, based on the first start location and a reference distance, a second start location of second compressed data in the first compressed data, wherein the reference distance is a maximum distance value between any first data segment in the target data and each data segment referenced by the target data;
• determine, based on the first start location and the first length, a first end location of the second compressed data;
• and
• decompress, based on the second start location and an end location, the second compressed data to obtain the target data.

A computer program product comprising instructions that are stored on a computer readable medium and that, when executed by one or more processors, cause a compute device cluster to:

• obtain a data processing instruction to decompress first compressed data to obtain target data, wherein the first compressed data comprises a compressed data group that comprises the target data, and wherein the data processing instruction comprises a first start location of the target data in the data group and a first length of the target data;
• determine, based on the first start location and a reference distance, a second start location of second compressed data in the first compressed data, wherein the reference distance is a maximum distance value between any first data segment in the target data and each data segment referenced by the target data;
• determine, based on the first start location and the first length, a first end location of the second compressed data;
• and
• decompress, based on the second start location and an end location, the second compressed data to obtain the target data.
